Pulse shaping in digital communication

Perhaps the most common pulse-shaping filter type used in communication systems is the Raised Cosine or Root Raised Cosine filter. The name comes from the shape of the spectral response, where the transition band of the filter follows a half-cycle of a raised cosine shape. ECE 461: Digital Communication Lecture 8b: Pulse Shaping and Sampling Introduction Information is digital in today’s world but the physical world is still analog. Digital commu-nication entails mapping digital information into electromagnetic energy (voltage waveforms) and transmitting over an appropriate physical medium (over a wire or wireless).

Therefore, the pulse shaping filter will need to interpolate by at least a factor of two, and is often interpolated significantly higher than this.

Intersymbol interference can disrupt the reception of signals. Learn how to mitigate this issue using Nyquist pulse shaping techniques. In electronics and telecommunications, pulse shaping is the process of changing the waveform of transmitted pulses. Its purpose is to make the transmitted signal better suited to its purpose or the communication channel, typically by limiting the effective bandwidth of the transmission.
