Figure (1) shows the block diagram of a wideband frequency mođulator 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 f-0.1 MHz by erystal- controlled oscillator also B0.2, a second crystal- controlled oscillator supplied a sinusoidal wave of frequency 9.5 MHz to the mixer.
