What is pulse shaping in digital communication?
In electronics and telecommunications, pulse shaping is the process of changing the waveform of transmitted pulses to optimize the signal for its intended purpose or the communication channel. This is often done by limiting the bandwidth of the transmission and filtering the pulses to control intersymbol interference.
Why is pulse shaping technique used?
Why is pulse shaping technique used? Explanation: Pulse shaping techniques reduces the intersymbol interference. They are also used to reduce the spectral width of the modulated digital signal.
What is a pulse shaping filter?
A pulse shaping filter is used in communication channels to manipulate a waveform or pulses to have the desired shape in the time domain. A pulse shaping filter can be a physical circuit, but normally it's a mathematical function that is used as a signal processing algorithm.
What is Nyquist pulse shaping?
Pulse shaping is one technique used in communication to overcome the degradation of signals due to ISI. Pulse shaping involves the process of choosing the time-domain and spectral shape of the symbols so that the pulses do not spread or overlap.
