Raised cosine filter for transmit pulse shaping

by Krishna Sankar on April 22, 2008

Time domain response of raised cosine filter

In the previous post on transmit filtering using Nyquist pulse, we had briefly learned that the information symbol with a symbol period can be transmitted without inter symbol interference (ISI) by using Nyquist pulse, . [...]
