(b) An analog signal x(t) = 27. 6000t is sampled at a rate of 0.5 higher than Nyquist rate. The quantization step amplitude level is set within 500 to 1000 to conserve transmission bandwidth as much as possible. The A/D conversion uses PCM with linear quantization and binary encoding as well. Calculate the minimum bandwidth of the channel's transmission. (c) The PSK modulator system has a simusoidal carier signal with 10V amplitude and fluctuating at 40000n radians/s. The bipolar 4-bits binary data input, 1011 with a bit- rate of 10kbp is modulated with the carrier to form a modulated PSK signal. Sketch the resulting PSK signal completely.

Concept explainers

Fiber Optics

Fiber optics is a technology used to transmit the facts such as light or pulses with fiber or plastic over long distances. Visual fibers are about the width of a human hair strand and, when tied directly to a fiber-optic cable, can transmit multiple long-distance records and faster in different ways.

(b) An analog signal x(t) = 27. 6000t is sampled at a rate of 0.5 higher than Nyquist
rate. The quantization step amplitude level is set within 500 to 1000 to conserve
transmission bandwidth as much as possible. The A/D conversion uses PCM with
linear quantization and binary encoding as well. Calculate the minimum bandwidth of
the channel's transmission.
(c) The PSK modulator system has a simusoidal carrier signal with 10V amplitude and
fluctuating at 40000rn radians/s. The bipolar 4-bits binary data input, 1011 with a bit-
rate of 10kbp is modulated with the carrier to form a modulated PSK signal. Sketch
the resulting PSK signal completely.

In three-level PWM, the modulating process operates on each portion of the modulating function separately. The output peak value is still given by the depth of modulation, but the RMS value of the square wave is not Vin. Compute the THD for three-level PWM as a function of the depth of modulation (modulation index k).
