We designed FM receiver circuit with minimum components - Transistor BF495, resistor, coil, capacitors for local FM reception.

The following circuit should prove particularly interesting to those readers considering building their own FM tuner. The novel feature of the circuit is that the well-known CA 3089 IC is not used as ...

Not only is the composite demodulation described in this article useful as a confidence check and troubleshooting aid, but in the age of FM translators for struggling AMs, the convenience of having ...

Gong, Z. (2018) Design of FM Modulation and Demodulation Circuit Based on Matlab. Signal and Information Processing, 1.

For example, if I wanted to modify the FM pass-band width on an 857, I could update the FM demodulation circuit by replacing a couple of components. On a 7300, I could not because there is no circuit.

A tuned circuit picks the frequency and a detector — usually a diode — demodulates the signal directly.

For the 74HCT4046A, logic 1 at the inhibit input (pin INH) disables the vco and demodulator, while logic 0 turns both on. For the 74HCT9046A, logic 1 on the inhibit input disables the whole circuit to ...
