[Question] R06-A-2 Which of the following combinations of terms fit (a) and (b) in the [ ] of the following statement regarding a toroidal iron-core coil? "When the current flowing through a coil changes, the coil's [(A)] also changes, generating an induced electromotive force in the coil itself. In the toroidal iron core coil shown below, with the primary and secondary coils wound around it, if there is no magnetic flux leakage, the change in the secondary coil's [(A)] is proportional to the change in the primary coil's current. Therefore, the induced electromotive force in the secondary coil is proportional to the change in the primary coil's current, and the proportionality constant in this case is called [(B)]." [Question] R06-A-3 When a 400 kΩ series resistor is connected to the 50 V voltmeter shown below, measuring a voltage of 40 V, the voltmeter shows a reading of 8 V. Which of the following is the appropriate combination of the voltmeter's internal resistance rv [kΩ] and the value of the series resistor Rm [kΩ] that should be connected to enable the voltmeter to measure a maximum voltage of 300 V? [Question] R06-A-4 In the RLC series circuit shown below, when the AC power supply voltage E = 100 V, resistance R = 10 Ω, inductive reactance XL = 12√3 Ω, and capacitive reactance Xc = 2√3 Ω, what is the appropriate value for the magnitude of the current I [A] flowing through the circuit? [Question] R06-A-5 For four events P(i) (i = 1 to 4) that can occur from a certain information source, if the respective occurrence probabilities are P(1) = 1/2, P(2) = 1/4, P(3) = 1/8, and P(4) = 1/8, what is the appropriate value for the average information content (entropy) H [bit] of this information source? [Question] R06-A-6 When transmitting an audio signal with a maximum frequency of 8 kHz in real time using pulse code modulation (PCM) encoded in 8-bit binary notation, what is the minimum required transmission rate S (kbps)? [Question] R06-A-7 As shown in the diagram below, System 1 with an availability rate A₁ = 0.90 and System 2 with an availability rate A₂ = 0.90 are connected in parallel, and System 3 with an availability rate A₃ = 0.80 is connected in series. What is the appropriate value for the overall availability rate At of the computer system? [Question] R06-A-8 When subtracting decimal numbers (141)₁₀ - (65)₁₀ using binary complement notation, which of the following combinations of terms fits (A) and (B) in the following calculation process? [Question] R06-A-9 In the logic circuit shown below, which of the following is the logical expression for output F? However, for logical variables A and B, A+B represents the logical sum, A*B represents the logical product, and Ā represents the negation of A. [Question] R06-A-10 In the static characteristics of the transistor (common emitter) shown below, which of the following is the DC current gain hFE when VCE = 5 V and IB = 10 μA? Here, IB represents the base current, Ic represents the collector current, VBE represents the base voltage, and VCE represents the collector voltage. [Question] R06-A-11 Which of the following statements regarding the phase-shift keying (PSK) digital modulation method is incorrect? 8PSK is more resistant to phase changes due to noise during transmission and has better error characteristics than QPSK. [Question] R06-A-12 OFDM uses guard bands between subcarriers to prevent adjacent channel interference. [Question] R06-A-13 Which of the following statements about the protocol layers of the OSI reference model is accurate? The OSI reference model classifies and organizes communication functions into seven layers. It serves as a guideline for understanding protocol design and functionality in computer networks. [Question] R06-A-14 Which of the following statements about the functions of a database management system (DBMS) is accurate? Database operation functions refer to functions that update data and retrieve data in response to user queries. [Question] R06-A-15 Which of the following statements about the functions of a computer's operating system is inaccurate? User management is the function that manages the allocation of main memory to multiple programs running on the computer. [Question] R06-A-16 Which of the following statements about character data representation methods (character codes) is inaccurate? ASCII is a character code established by the American National Standards Institute (ANSI) and includes alphabets, numbers, symbols, half-width katakana characters, and control symbols. [Question] R06-A-17 Which of the following best describes the amplitude characteristics of the output signal Vout when an input signal Vin is applied to the filter circuit shown below? [Question] R06-A-18 Which of the following is not a best statement about semiconductors? In an n-type semiconductor, where donors such as arsenic are mixed into an intrinsic silicon semiconductor, the number of free electrons is fewer than the number of holes. [Question] R06-A-19 In the Hartley oscillator circuit shown below, if the inductances of the two coils are L₁ [H] and L₂ [H], respectively, the mutual inductance between the two coils is M [H], and the capacitance of the capacitor is C [F], what is the best formula for calculating the oscillation frequency ƒ [Hz] of this circuit? [Question] R06-A-20 Which of the following statements regarding optical modulation methods is inaccurate? Direct modulation, when modulated at high speeds, causes chromatic dispersion, a phenomenon of wavelength fluctuation during modulation, limiting transmission distance. [Question] R06-A-21 Which of the following statements regarding repeaters in optical fiber communications is inaccurate? A 3R regenerative repeater converts optical signals into electrical signals using photodetectors, performs equalization and amplification, timing extraction, and multiplexing, then converts the signals back into optical signals for transmission. [Question] R06-A-22 Which of the following statements regarding SIP, which is used in IP telephony, etc., is inaccurate? The SIP message body is used to notify information such as the media used and port number after session establishment and is written in RTP (Realtime Transport Protocol). [Question] R06-A-23 Which of the following statements regarding coaxial cable is inaccurate? Compared to waveguides, coaxial cable has less loss, and the loss value decreases as the frequency increases. [Question] R06-A-24 Which of the following statements about Rayleigh scattering loss, a cause of optical loss in optical fibers, is accurate? Due to variations in the density of the glass in an optical fiber, the refractive index varies slightly from location to location. This fluctuation in refractive index causes light to scatter, resulting in loss. [Question] R06-A-25 Which of the following statements about wireless LAN standards is inaccurate? IEEE802.11a uses radio waves in the 2.4 GHz band and employs direct spread spectrum technology.
