5.5.2 Matched-filter type demodulator A Matched Filter (MF)to s(t)is defined as a LTI filter whose impulse response is as h(1)=Cs(T-1),where C is any non-zero constant and T is a given sample-time.. 中() )dt (T-0 ()d 2(T-0 r(r) r(0 A matched filter is equivalent to a correlator. w(T-) An alternate demodulator is as Fig 5.35 on page 276.
