1. Asuuming that an 8-bit ADDC channel accepts analog input ranges from 0 to 12 volts, determine the following:
a) number of quantization levels
b) step size of the quantizer
c) Quantization level when the analog voltage is 9.25 volts
d) binary code produced by ADC
e) Quantization error
2. a)Write the diffrenece equation for a four-term moving average filter.
b) The input x[n] = cos(n pi/6)u[n] is passed through the four-term moving average filter. Solve for the first 5 samples of the output.
c) Given a sampling frequency of 10 kHz, which input frequency would be able to eliminate completley with this moving average filter?
