1.	____ filter is required to form ____ filter.(a) Two raised cosine filter, one sinc filter(b) Two raised sinc filter, one raised cosine filter(c) Two root raised cosine filter, one raised cosine filter(d) Two raised cosine filter, one root raised cosine filterThis question was addressed to me during an interview for a job.Enquiry is from Techniques in section Cognitive Techniques of Cognitive Radio
Answer» The correct choice is (c) Two root raised cosine filter, one raised cosine filter Easy EXPLANATION: Two root raised cosine filter is required to FORM one raised cosine filter. It may be USED to reduce inter-symbol interference. It involves installing one root raised cosine filter at the transmitter and the other filter at the receiver.
