What is Understanding Pulse Amplitude Modulation about?
This chapter discusses serial pulse amplitude modulation (PAM), where a pulse is amplitude modulated according to data symbols and transmitted over a channel. The Nyquist criterion states that the bandwidth W of the modulation pulse must be greater than 1/(2T) to avoid intersymbol interference, where T is the time between pulses. This ensures the pulse shifts are orthonormal and the data can be perfectly reconstructed. Harry Nyquist developed this important result on bandwidth necessary to avoid interferenc
