1) A 6-bit A/D converter with a full-scale voltage of 20 V is to be employed in a binary PCM system. The input analog signal is adjusted to cover the range from zero to slightly under 20V, and the converter is connected for unipolar encoding. Rounding is employed in the quantization strategy. Determine the following quantities:
a) normalized step size
b)actual step size in volts,
c)normalized maximum quantized analog level
d) actual maximum quantized level in volts
e)normalized peak error
f) actual peak erro in volts
2) A baseband signal frequency componets from dc to 8kHz. Determine the:
a) Theoretical minimum sampling rate and b) maximum time interval between successive samples.
