What is the envelope detector?
A simple electronic circuit that grabs a high -frequency signal as an input, repairs it and releases a new signal as an envelope for the original signal, is called the envelope detector. LED detectors and accurate rectifiers are often combined to improve performance. Common applications include sound devices such as electronic tools and portable radios. Simplicity and efficiency are perhaps the most important advantage of the envelope detector. Several disadvantages of using these devices are often balanced by advantages. Essentially, the rising edge of the signal is stored in the capacitor. As the input signal decreases, the energy stored in the capacitor flows through the resistor as a new signal output. In most envelope detectors, the diode is also part of the perimeter, and this diode usually corrects the signal and creates an output.
LED detectors usually have all the necessary parts to accept and feared the signal and create the desired output. However, to clean the envelope, a precise rectifier is often added to the diode detector. It canfilter out other input signals and leave only the required input to convert to a better output.
Many applications for the envelope detector are related to the sound device. For example, many electronic musical instruments such as an electric guitar or bass can use some form of an envelope detector to change the sound. In addition, portable radios almost always contain a simple envelope detector that can receive and translate radio signals into sounds.
Several advantages have caused the envelope detectors to be useful in many applications. Perhaps the most important thing, the envelope detector is often considered simple because it contains only a few elements can cause the desired effects. This simplicity usually means that the cost of the envelope detector is also low. Once it is configured to a specific task, most envelope detectors are also reliable and accurate.
disadvantages of using the detectorThe envelopes are usually associated with the possibility of distortion. For example, most radios have less than perfect sound quality due to inconsistent input signals that create inconsistent or low envelope quality. In addition, many of these detectors are sensitive to noise from other types of transmission and the input must be filtered to compensate. However, many of these disadvantages are acceptable due to the value of the envelope detectors in general.
