A signal, m(t) which is bandlimited to 20 KHz, is going to be transmitted over a channel

a) If the stepsize must be less than    \(.002 m_{p}\) and the number of steps mut be a power of 2, calculate the minimum number of bits that satisfies this criteria.

b) If this bitstream was transmitted, what would be the minimum channel bandwidth?

c) If a parity bit is added, what would the new channel bandwidth be?

d) If the signal must be sampled at a rate 20% faster than the Nyquist rate, calculate the minimum sampling frequency and channel bandwidth (assume no parity bit).
