FM receivers with PLL
This article discusses simple FM direct conversion radio receivers utilizing a phase-locked loop (PLL). These receivers operate by locking the local oscillator frequency to the input signal. All FM receivers are based on a circuit that combines an oscillator and...
Superlinear FM (Frequency Modulator)
Designing various electronic circuit systems (synthesizer, modem, decoder, data converter, etc.) often requires a frequency modulator subsystem. An FM modulator is a crucial component in these systems.
An FM modulator is an electronic device that encodes information in a carrier wave...

The transmitter's function is to modulate the original signal frequency of the message-carrying signal, a process known as modulation. The circuit realization of this function is referred to as a frequency modulation (FM) circuit. FM tuners are categorized into direct...
Automatic Frequency Control FM reciever
This is a measurement I did on a FM receiver (MC3372). I have plotted the output DC-bias as a function of the IF (Intermediate Frequency) frequency. At 455kHz you can see that I have 5.5V DC bias. When I change...
carrier current fm receiver
Input signals from the power line are coupled through C23 and R19 to the input filter network. C23 must be rated at 600 volts. Switch 52 is used as an attenuator. Components C2 through C7, L1 through L3, R1, and...
TDA7000 FM Radio Receiver Circuit
The TDA7000 is a monolithic integrated circuit designed for mono FM portable radios or receivers, emphasizing minimal peripheral components for compact size and cost-effectiveness. This integrated circuit features a Frequency-Locked-Loop (FLL) system with an intermediate frequency of 70 kHz. Active...
