Q1: Choose one of the choices indicated in the parentheses such as the following sentences have a correct meaning: 1. BW of unipolar RZ, is_ the BW of unipolar NRZ. (smaller than, equal to, greater than, much smaller than). 2. In Binary Phase Shift Keying system, the binary symbols 1 and 0 are represented by carrier with phase shift of (n/2, x, 2n, n/4) 3. Quantization is a process. (nonlinear, reversible, nonlinear & reversible, none of the mentioned) 4. The differential pulse code modulation (DPCM) receiver consists of three main stages, and low pass filter. (quantizer, digital to analog converter, expander, accumulator, sampler) 5. In which modulation type, the bit rate can be three times the baud rate (ASK, FSK, PSK, none of them) 6. broadcast of FM occurs in the 88-108 MHz range. (commercial, traditional, economical, . terrestrial) 7. In Frequency Modulation, (Amplitude of the carrier remains same, Frequency of the carrier varies in accordance with the modulating signal, The number of side bands are infinite, All of the above) 8. A 100 MHz carrier is frequency modulated by 10 KHz wave. For a frequency deviation of 500 KHz, the modulation index of the FM signal- (20, 50, 100, 200) 9. Wide band FM has the characteristics:_ (The frequency constant kr is large, Bandwidth is wide, Both a and b, None of the above) 10. For an FM signal v(t) = 15 cos ( 10 * 10% +10 sin 1220t), calculate, Modulating frequency (159.1 MHz, 350.1 MHz, 159.1 Hz, 194.1 Hz)
