In the final receiver, the RF amplifier can be deleted altogether,and the LC tank circuit described will drive a mixer input through alink-coupling circuit.The local oscillator (LO) problemThe local oscillator circuit must track the RF amplifier and must also tune afrequency range that is different from the RF range by the amount of the IF ...

With such a circuit, almost puresine-wave voltage will be developed acrossthe tank circuit even though power is suppliedto the tank in short pulses or spurts, so longas the spurts are evenly spaced with respectto time and have a frequency that is the sameas the resonant frequency of the tank.Another way to visualize the action of thetank is to ...
