Binary frequency-shift keying is used to transmit the message. A sinusoidal waveform s () with frequency f =100/7, is used to transmit one, while a sinusoidal waveform s, (t) with frequency f, = 120/7, is used to transmit zero. (a) If the energy per bit is one and the bit rate is one bit/s, what are single pulses of s (t) and s, () ? Sketch them in the time domain. (b) Sketch the frequency spectra of single pulses of s (1) and s, (t) Suppose that the binary input message is given as: 1 if ne { - 1,0} m [n = o if - co
