Compute the Nyquist sampling rates of the following two signals: x2(t) = sin(6πt)sin(4πt) x3(t) = (sin(6πt)sin(4πt))/t2

What is alpha?

Q4. The signal x(t) given by, x(t) = 1+2 sin(80nt) + 1.5 cos(300nt) + 0.5 cos(375t) + 0.7sin (815at) is applied to the following system LPF ADC Digital x(t) Fc=400 Hz FSAM? Processor a. Find the minimum sampling frequency that can be used by the Analog to Digital Converter, ADC, given that the Low Pass Filter, LPF, is ideal. Justify your answer. b. Each sample is then quantized (“measured") by comparing the amplitude of each sample to a standard set of 1024 levels. Determine the total number of bits generated in a six-minute interval. c. If the range of the ADC is ± 5 V, detrmine its resolution, A, and it's quantization error.
