An 8-bit ADC converts an analog input voltage level into 28 code levels ranging from 0 to 28 -1. If the ADC is excited by a 1024-point full-scale sine wave described by 0.5sin 2 1/1024 0.5, 0,1,...,1023, ( π ⋅+ = n n ) what is the expect number of codes appearing at the output corresponding to code 0? What is the code count for code 28 -1? What is the distance between adjacent code edges?
