FM transmitter circuit

Tro telephones can be utilized as an intercom through the implementation of this circuit. Traditional rotary phones, particularly those that are non-electronic, may be the most effective for this purpose. Additionally, this method can also power handsets alone. The circuit...

The circuit operates by utilizing a high-frequency section of the antenna to receive AM radio signals, amplifying radio-frequency signals at a selected vibration level of 465 kHz. The intermediate frequency (IF) signal is processed through an IF amplifier, followed...

Developed as an interface between the General Instruments AY-3-8500-1 TV game chip and the antenna terminal of a TV set. Adjust capacitor C1 to the frequency of an unused channel to which the receiver is set for playing games....

This circuit was designed in response to a request for a 1 kHz infrared (IR) transmitter circuit suitable for remote control applications. It is intended to serve as a low-power IR transmitter with an operating frequency of 1 kHz,...

This circuit was first introduced by Signetics Corporation as the SE555/NE555 around 1971. Pin connections and functions are as follows: Pin 1 (Ground) is the most negative supply potential of the device, typically connected to circuit common when powered...
