What is used for pulse shaping?
The Gaussian filter is a pulse shaping technique that is typically used for frequency shift keying (FSK) and minimum shift keying (MSK) modulation. This filter is unlike the raised cosine and root raised cosine filters because it does not implement zero crossing points.
What is pulse shape 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 does a shaping amplifier do?
Use of shaping amplifiers will reduce the fall time of the pulse signals, reducing the incidence of pulse 'pile up', and improve the signal-to-noise of the detection system. The shaping time is defined as the time-equivalent of the "standard deviation" of the Gaussian output pulse.
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.
