Superheterodyne Fm Receiver Schematic. Frequency can changed by adjusting of variable capacitor c3. The trick is to break down the circuit into its individual parts and work on each part separately.
The output of the if amplifier is applied to the limiter circuit. The limiter removes the noise in the received signal and gives a constant amplitude signal. The if signal is then amplified by a strip of if amplifiers and then fed into a detector that outputs the audio signal into an audio amplifier that powers the speaker.
As a result of its advantages the superheterodyne receiver has remained as one of the foremost techniques used in radio technology.
A superheterodyne receiver uses signal mixing to convert the input radio signal into a steady intermediate frequency if that can be worked with more easily than the original radio signal that has a different frequency depending on the broadcasting station. Although today other techniques are coming to the fore increasingly nevertheless the superhet receiver is still very widely used in view of the benefits it is able to. Repairs this tuner was purchased at a swap meet. The trick is to break down the circuit into its individual parts and work on each part separately.
