Remote Control Receiver circuit diagram

This preamplifier and tone control circuit utilizes a JFET to maximize its performance as a low-noise, high-input impedance device. All device parameters are non-critical, yet the circuit achieves harmonic distortion levels below 0.05% with a signal-to-noise ratio exceeding 85...

Presented circuit is very simple. With more sampling, I refrained from using the converter and lamp designed for powering three NiCd or NiMH batteries. Because the voltage difference between the battery and the LED is very small, this arrangement...

To ensure proper operation of the transistor in a circuit, it is essential to measure the reverse breakdown voltage of the transistor. This is particularly important for tubes with high reverse breakdown voltage requirements, such as those used in...

A simple 16-volt switching power supply circuit can be constructed using the provided diagram, which is based on the MAX668 constant-frequency, pulse-width modulating (PWM), current-mode DC-DC controller. This integrated circuit is designed for a wide range of DC-DC conversion...

The final article on bipolar junction transistors (BJT) presents a variety of circuits, some practical and others more experimental. These circuits are capable of amplifying signals, filtering high and low frequencies, generating white noise, and flashing lamps. They can...

This document outlines a CMOS circuit designed for time adjustment in a spot welder. The circuit allows for the selection of a number of cycles, ranging from 1 to 99, with practical applications typically using around 10 cycles. The...
