Why the output of the envelope detector changed frequency when the audio frequency was varied?
answer for me please
Am detector wave form?
It is high frequency carrier signal and low frequency carrier signal in Am detector in the same way of wave form as a result of graph...
What is the frequency that a smoke detector alarm can be heard at?
Most smoke alarms are about 3000 Hz according to Wikipedia, but they do make them in different frequencies for the hearing impaired.
How do u use PLL as FM detector?
To use the PLL (Phase Lock Loop) as FM detector, you need to know the Free-running frequency.
How to trip a motion detector?
A: There are photo detector that sense changes in light as movement and there are frequency detectors that sense frequency shift as a person disturb the signal. Both are effective withing a certain range depending on environment and sensitivity. HOW TO TRIP IT IS UP TO YOU.
How are coins found using a metal detector?
Coins are found by the detector sending a pulse which picks up metal signals. Now there are two types a low frequency and a pulse indicator, the low frequency is used to pick up deeper objects
What is mien by carrier frequency?
High range of frequency that carries the message signals in transmission of data.after receiving the signals, the detector seperate the message and carrier .
What is the function of intermediate frequency transformer?
intermediate frequency transformer (ift) acts as a band selective n/w. the ift which is 455 khz is then given to IF amplifiers which is then given to detector.
How phase lock loop is used as a universal detector for Amplitude Modulation?
I could certainly be wrong, but my recollection is that a phase locked loopis a universal detector for Frequency and Phase modulation, and is quiteinsensitive to Amplitude modulation.
Am demodulator diode detector circuit?
demodulator circuit is a circuit which is used for remove all high frequency components from modulated signal.
How does the Escort Radar Detector work?
The Escort Radar Detector scans for the radio frequency waves of most police department speed guns. These speed gun frequencies can be detected for about a mile before actually seeing the police officer.
Can a kid make a trap with only string a motion detector and a Nerf gun?
Yes, and you wouldn't need the motion detector.
