Baseband digital trnamission and multi level coding

A baseband digital data link transmits polar binary NRZ current pulses at a rate of 1.0 Msps. The link uses ideal RRC filters with roll off factor r = 0.5.

a. Calculate the bandwidth occupied by the baseband binary signal.

b. If the available channel bandwidth is 0.5 MHz, which of these can be used to transmit the digital data successfully?

2-ASK 4-ASK 8-ASK BPSK BFSK

c. The E1 transmission system transmits voice signals using 8 bit words. What is the number of voice channels in an E1 frame?
