What else can I help you with?
What is the difference between the modulating signal and the demodulating signal in output of the detector?
Distortion.
What is the operation of amplitude modulation detector?
An amplitude modulation (AM) detector demodulates the received AM signal to retrieve the original audio or information signal. This process typically involves rectifying the AM signal to remove its negative half-cycle, followed by filtering to smooth out the resulting waveform. The output is then amplified and can be further processed to restore the original audio signal. Commonly used detectors include envelope detectors and synchronous detectors.
What is the use of crystal detector in electronics?
A crystal detector is a diode, often used in non-powered radio receivers. It conducts at a much lower voltage than a typical silicon diode, making it easier to generate the signal amplitude required from the tuning circuit.
What are the application of peak detector?
to detect maximum peak os AC signal and convert to DC signal
How the envelope detector converts a 455 khz am signal to the message signal?
The diode flips the entire signal to the positive region like a rectifier. Then the parallel rc combination is kept charged or discharged by the carrier frequency, 455kHz. Since the Signal sits on top of the carrier, the output is the original sent signal with some ripple distortion, this can be taken care of with a simple lowpass rc filter
What is detector mount in waveguide and its function?
used to detect the microwave signal
What is the function of detector in UV spectrophotometer?
Detector converts optical signal to electric signal
What is diode detector?
there are two types:- 1) simple diode detector 2) practical diode detector the diode is common device used in am demodulator. signal(am demodulator signal ) is applied anode and output is taken from cathod
Is flame detector an analog or digital signal?
digital signal
What is the difference between photon detector and thermal detector?
The wavelength of the detected signal.
Is envelope detector is a differentiators?
An envelope detector is not a differentiator; instead, it is a type of demodulator used primarily in amplitude modulation (AM) systems. It retrieves the envelope of a modulated signal to extract the original information signal. While both envelope detectors and differentiators involve signal processing, their functions and applications are distinct. The differentiator focuses on deriving the rate of change of a signal, while the envelope detector is concerned with capturing the modulation envelope.
What is the square law detector envelop detector?
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 is the difference between the modulating signal and the demodulating signal in output of the detector?
Distortion.

What is the use detector in wireless communications?
The detector detect the audio signal in the received modulated RF signal, rectify it and filter the RF to ground and pass the pure audio to the next stage
Where you use of diode 1n34?
The 1N34 is a germanium signal diode, so it would be used as a detector/mixer in a.m. reception for example.
Am demodulator diode detector circuit?
demodulator circuit is a circuit which is used for remove all high frequency components from modulated signal.
