Amplitude Modulation And Demodulation Circuit Diagram

Amplitude Modulation And Demodulation Circuit Diagram is a complex electrical device that is used to modulate and demodulate signals between two devices. It is commonly utilized in radio systems, but is also applicable for other communication systems like telecommunications, digital audio, and satellite communications. This device is usually made up of an oscillator, an amplifier, and a detector. The oscillator serves as the source of the signal that is to be modulated and demodulated. The amplifier allows the signal to pass through with minimal losses while maintaining its amplitude. The detector, on the other hand, captures the signal and sends it back to the source, thus allowing information to be exchanged between the two systems.

A typical Amplitude Modulation And Demodulation Circuit Diagram contains numerous components like resistors, capacitors, transistors, diodes, and coils, which are typically arranged in a specific configuration. For example, the oscillator may consist of a few tuned circuits while the detector might utilize a detector window. To begin operation, the oscillator produces a sinusoid, which is then amplified and sent to the detector. Once the signal is detected, the detector window helps to shape the signal by removing certain frequencies and amplifying others. The result is a signal with the desired characteristics, such as amplitude, frequency, phase, and bandwidth.

The demodulation process involves reversing the process, where the detector window receives the signal with the characteristics of the desired signal and creates a waveform corresponding to the original signal's characteristics. This process requires the use of a comparator circuit, in which the original signal's characteristics are compared to the waveform created by the detector. If these characteristics match, then the original signal is demodulated. This type of circuit is frequently used in radio receivers, wherein the detected signal is filtered so that only the desired frequency is allowed to pass. Along with the receiver, this device is also used in satellite receivers, TV antennas, and telecommunication systems.
