calculate each part please and show the answers for each part step by step

a) A bandpass data transmission schemes uses M - ary PSK over a 120kHz channel. The minimum required bit rate is 900kbits/s. Suppose the channel is ideal nyquist channel, what is the minimum SNR in dB is required to maintain reception with a probability of bit error no worse than 106 ? b) It is required to transmit 2.08106 binary digit / sec with a binary digit error probability of Pe
