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)....
