AM FM Simultaneous Transmitter Using Digital IC
We are familiar with transmitters either working in AM or or in FM.But this circuit transmits both am and fm signal simultaneously at two different frequencies AM in 20 Mhz and FM in 100 Mhz.
The 5th harmonics of the fundamental is used to transmit the fm signal,hence it's range will be less than am signal One can also directly feed the audiosignal .Transistors Q1, Q2 forms the amplifier stage which is fed to the modulator formed by the nor gates .Use a long wire antenna for good reception
