The square law detector, also known as an envelope detector, is a circuit used in radio systems to demodulate amplitude-modulated (AM) signals. It works by squaring the incoming signal, which enhances the envelope of the modulation, and then filtering out the high-frequency components to retrieve the original message signal. This simple method allows for effective extraction of the audio or data signal carried by the AM wave. The envelope detector is particularly valued for its ease of implementation and effectiveness in various communication applications.

What are the different types of distortions that occur in an envelop detector?
The main types of distortions that can occur in an envelope detector include amplitude distortion, phase distortion, and frequency distortion. These distortions can affect the accuracy of the envelope detection process and result in errors in recovering the original signal. Techniques such as filtering and adjusting the envelope detector circuit parameters can help reduce these distortions.
What is advantage and disadvantage of coherent detector - envelop detector?
The advantage of a coherent detector, such as an envelope detector, is its ability to accurately demodulate amplitude-modulated signals by effectively recovering the original message signal with minimal distortion, even in the presence of noise. However, a disadvantage is that it requires a synchronous reference signal, which can complicate the design and implementation, especially in environments where maintaining synchronization is challenging. Additionally, envelope detectors can struggle with signals that have rapid amplitude variations.
What is square law detection?
Square law detection is a method used in communication systems to demodulate analog signals. It relies on multiplying the input signal with itself to obtain the power of the signal, which contains information about the original signal. This method is commonly used in amplitude modulation systems for recovering the original message signal.

Are envelop and envelope the same?
Envelop is a verb -- to wrap up (e.g., envelop oneself in a cozy blanket); envelope (noun) is a wrapper, usually for mailing.
What is the purpose of a Whistler radar detector?
The purpose of a Whistler radar detector is to detect the speed of the motorists, if it is being monitored by police or law enforcement by a radar gun.
Is it legal not to own a carbon monoxide gas detector in the US?
I believe that it is law in some states to have a carbon monoxide detector, but regardless of whether or not it is law, it would be extremely wise to invest in a good working carbon monoxide gas detector. It is an odorless gas, and is a silent killer. Do yourself a favour and replace the one that is not working.
Why do they not apply a lie detector test in the court of law?
Lie detector test is one of the due process investigation of the suspect. but this is not the basis of the case if the suspect is guilty of the charges.
