This whistle light switch allows for the control of lighting installations. The primary component of this circuit is the UM3763 integrated circuit, manufactured by UMC. A piezo-ceramic buzzer serves as a microphone, detecting sound frequencies between 1.2 kHz and...
This is a circuit design for an FSK demodulator, which is an electronic device that converts an FSK signal into a serial digital signal. FSK modulation is used to transmit digital serial data, and demodulation is necessary to retrieve...
A precision oscillator can be constructed using a quartz crystal; however, with appropriate component selection, it is also possible to build one using an RC (resistor and capacitor) circuit. An RC oscillator generates an oscillating signal through the use of...
The circuit diagram represents a booster for an audio application. It features a linear potentiometer R5 with a resistance of 100K ohms, which includes an on/off switch. The capacitor C1 should be selected with a value between 0.05 µF...
