WebIn Figure 17.8 the frequency response of the raised cosine filter is shown. To better see the passband shape, it is plotted linearly, rather than logarithmically (dB). It has a cutoff frequency of 500 kHz, the same as our ideal low-pass filter. A raised cosine filter response is wider than the ideal low-pass filter, due to the transition band. Web1 Answer Sorted by: 2 Think of the root-raised cosine as a family of functions. The roll-off factor is a parameter that chooses one of the possible functions. All root-raised cosine pulses look similar to the sinc pulse. The interesting thing about the roll-off factor is that it controls two features of the function:

WebElectrical Engineering questions and answers. In the transmit chain you have specified the pulse shaping filter using the raised cosine equation. Here, in test point (Test 6), the low pass filter is also specified using raised cosine parameters. However, in practice, we almost always design the transmit and receive filters using a Root Raised ...
