One period of a real-time signal x(t) =2Sin(20*pi*t) , starting at t=0, has to be processed in a 4-bit digital computer. The A/D card have a sampling frequency of 55Hz and the input range is +/- 2Volts.
i) What are the values recorded in the sampled signal x[n] ?
ii)What is the resulting quantized signal?
iii)What is the resulting digitized/coded signal?
iv)If the sampled signal x[n] was filtered using a moving average filter of length 3 , what would the filtered signal be?
