Generate a sine wave signal with amplitude A=1, and frequency=0.1592Hz. Using a uniform PCM method, quantize it ot a) 8-level and b) 16-level. Plot the original signal and the quantized signals on the same axes (time duration=10 sec). Compare the resulting quantization SNR in dB for both cases.
Explain the characteristics of electromagnetic waves and application to communications systems and determine the signal spectra for the content of complex waveforms
A pulse compression radar transmits rectangular chirp pulses with bandwidths of 500 MHz. What is the approximate slant-range resolution after Dolph-Chebyshev frequency weighting that results in 30-dB sidelobes
a) Design the doubler circuit shown in Figure 2, for which:D = d8 d4 d2 d1 and B = b8 b4 b2 b1 are each an 8421 BCD code digit. The circuit must implement the equation: 10C* + B = 2D + C
