Abstract
In one implementation, a receiver may have an analog front end with an amplifier to receive a radio frequency (RF) signal and a mixer to downconvert the signal to a baseband signal. Then, a demodulator may receive the baseband signal and obtain an audio signal therefrom. Still further, a controller may be coupled to receive a control signal corresponding to a variable impedance level, and control a local oscillator coupled to the mixer responsive to the control signal. The variable impedance may be controlled by a user to tune to the channel.
