4. A 70 year old man was taken to hospital due to chest pain the doctors immediately took him
to ICU and did the ECG. The ECG signal is analyzed on spectrum analyzer to find the
problem. Assuming that spectrum analyzer internally contains DSP system to do the given
task. The ECG signal taken from the patient has bandwidth of 70Hz in that the required signal
bandwidth is only 60Hz remaining part of the signal represent the noise. Design a DSP system
that accepts only the required signal and samples it and the sampled spectrum contains 40Hz
separation between neighboring spectral components and this discrete time signal is
transformed into frequency domain using 16 point DFT find the following.
i. Find the cutoff frequency of the antialiasing filter
ii. Find the sampling frequency of the sampler used
iii. Find the Frequency of X(4) and X(8)
iv. Draw the block diagram of the designed system
