Video Distribution Amplifier

Engineeering Projects
video distribution amplifier

Distribution of Video to various recorders or TVs without losses or distortion is quite difficult. Thus, in order to solve this problem we had posted the project video distribution amplifier During the distribution of the video some losses and distortion might occur to decrease the quality of the video, but don’t worry here is a simple electronics project to overcome the problem, This video distribution amplifier enables four video recorders or TVs to be connected to the output of one VCR or VCP. The circuit “Video Distribution Amplifier” can be…

Automatic Noise Limiter Circuit

Automatic noise limiter circuit

Man-made sources of external noise are extremely troublesome to highly sensitive communications receivers as well as to any other electronic equipment that is dealing with signals in the microvolt region or less. The interference created by these man-made sources, such as ignition systems, motor communication systems, and switching of high current loads, is a form of electromagnetic interference (EMI). Reception of electromagnetic interference by a receiver creates undesired amplitude modulation, sometimes of such large magnitude as to adversely affect Frequency Modulation reception, to say nothing of the complete havoc created…

laser based communication link transmitter circuit

Communication is an essential part of our daily life. The project; “Laser-Based Communication Link” allows people at a distance of around 500 meters to communicate wirelessly through a laser. Various other laser-based projects posted on bestengineeringprojects.com are:- (a) Speech Communication using Laser (b) Mini Laser Turret (c) Laser Voice Transmitter Circuit The project unlike other wireless media uses laser light from the transmitter torch as a carrier instead of RF signals used in the conventional system. At the receiver end, the phototransistor should be aligned in a line of sight position…

3.7V to 5V, 5.3V and 6V Converter Circuit

3.7v to 5v converter circuit

3.7V to 5V, 5.3V, and 6V Converter Circuit: The preferred voltage levels while working in most electronics projects lie between the value 5V to 6V. However, 3.6V-3.7V batteries are found abundantly in the market with a cheap price tag. So, we presented an economic solution to generate commonly used operating voltages i.e. 5V, 5.3V, and 6V using these cheap and easily available 3.6V and 3.7V batteries. Using two-three batteries of 3.6V (3.6*2=7.2V) and 3.7V (3.7*2=7.4V) doesn’t provide the desired voltage level and thus this project was essential. This DC-to-DC converter…

Arduino Based Music Player

arduino based music player

The project posted here is of simple music player system based on Arduino uno board and SD card module. As we all know that Arduino can deal with digital signals or square signals only if we wish to work with sine waves we have to use further processing circuits. Previously we had posted Tune Player using Arduino for demonstration of using PWM pin of Arduino. The audio signal is sine wave thus we have used PWM pin and OP-amp for audio output. In order to generate a pure audio signal…

In this section we are going to analyze and troubleshoot the AM converter circuit. the converter, also known as autodyne circuit, is a combination of the local oscillator and the mixer in a single stage. We are also going to discuss the power supply and audio amplifier problems in this section Upon completing this section, you should be able to Troubleshoot an AM converter circuit Identify an open input circuit Identify a dead or intermittent local oscillator circuit Identify causes for a dead and intermittent local oscillator Troubleshoot the receiver’s…

Complex sound generator

ic design complex sound generator

What is Complex sound generator? Internal noises; noise within a system, are treated as disturbances and we make attempts to reduce it to a lowest level possible. There is another way to eradicate noise and on the other hand, take benefits from the noise itself. It sounds completely insane, don’t you think so? The circuit we are going to discuss here reveals the mystery. The circuit entitled, ‘Complex sound generators’ makes use of this waste like internal noise and tones to produce special effect sounds.  The disturbance is thus replaced…

Organ Circuit | Top Octave Generator

IC design of organ cirucit

If you have observed quite a number of electronic projects, you must have noticed that different range of frequencies is used, sometimes all in a single project. To assist this requirement, this circuit “Organ Circuit” has been developed. The project entitled ‘Organ Circuit | Top-Octave Generator’ produces 12 distinct output frequencies. A single circuit produces 12 frequencies and each of them is different? Might sound a lot more complicated. However, the circuit uses only one parameter to serve this variation, which is the supplied input frequency to the chip. The…
