SOLVED: Figure shows the block diagram of a wideband frequency modulator using the indirect method. This modulator is used to transmit audio signals containing frequencies in the range of 100 Hz to 15 KHz. The narrowband is supplied with a carrier of frequency 1.0 MHz by a crystal-controlled oscillator. Additionally, a 8-0.2 second crystal-controlled oscillator supplies a sinusoidal wave of frequency 9.5 MHz to the mixer. The system's carrier frequency at the transmitter output is fc-LOOMHz. The
