You are given an analog-to-digital converter (ADC) which is used to convert an input analog signal to a digital signal. The highest frequency present in the input analog signal is 20 Hz. The ADC samples the input analog signal at 1.25 times the minimum required sampling rate. (Note; this ADC “over-samples” the analog input signal; the sampling rate of this ADC is higher than the minimum required sampling rate. The ADC samples at 1.25 times the minimum required sampling rate)....

A Digital Signal Processing system is taking at its input the following analogue signal s(t); s(t) - 20+ 20 cos(24xt)cos(xt), Where time t is expressed in ms. Part 1 - Setting the sampling frequency: (11 Marks) As a start, the system comprises only a sampler and an ideal analogue reconstructor as follows: w(t) s(t) Sampler Analogue Reconstructor s,(t) Figure a) Find the frequency spectrum S(t) of s(t) and deduce its bandwidth. You may directly use the table provided at the...

Signal Sampling Problem Hi! Good morning, can someone help me to solve this following sampling excercise? A digital communication link carries binary-coded words representing samples of an input signal Xa (t) = 3 cos 600πT + 2 cos 1800 πT The link is operated at 10000 bits/s and each input sample is quantized into 1024 different voltage levels. What is the sampling frequency and the folding frequency? What is the Nyquist rate for the signal Xa (t)? What are the...
