If the signal is processed by integrate and dump filter, what should be minimum Time T of the signal so that the error probability is not above 10 –4 . Q.2) Binary data is transmitted using PSK at a rate 2 Mbps over RF link having  bandwidth 2 MHz. Find signal power required at receiver input so that error  probability is less than or equal to 10 –4 . Assume noise PSD to be 10 –10 watt/Hz.  Q.3) Prove that “The performance of integrator and dump filter is identical to that  of the matched filter on the background of AWGN”. Calculate the probability  of error Pe. Q.4) A bipolar binary si
