WE CAN use the balanced modulator
& also the double balanced modulator(DBM)
THANKS.

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.
to detect maximum peak os AC signal and convert to DC 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
A voltage detector works by sensing the presence of an electric field around a live wire or electrical device. When the detector is brought near a voltage source, it detects the electric field and indicates the presence of voltage, usually through a light or sound signal. Some detectors use capacitive coupling to measure voltage without direct contact, while others may require contact with the conductor. They are commonly used to ensure safety when working with electrical systems.
used to detect the microwave signal
Detector converts optical signal to electric signal
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
digital signal
The wavelength of the detected signal.
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.

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...
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
The 1N34 is a germanium signal diode, so it would be used as a detector/mixer in a.m. reception for example.
demodulator circuit is a circuit which is used for remove all high frequency components from modulated signal.
There is a device called a radar detector, but it will only detect a radar signal, not police in general.
