g An analog voice signal, sampled at the rate of 8 kHz (8000 samples/second), is to be transmitted by using binary frequency shift keying (FSK). The modulator uses two frequencies 1 MHz and 1.2 MHz for signaling the logical bit values 0 and 1.

A transmission line has a velocity factor of 0.88. You desire to create a quarter-wavelength phasing section at an operating frequency of 150 MHz.
