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
According to 'Modern Control Engineering' written by Katsuhiko Ogata, the ratio fo the feedback signal, H(s)C(s)to the actuating error signal (R(s)-B(s)) is called the open-loop transfer function. Here, H(s) is the transfer function of the feedback signal detector, C(s) is the output signal and R(s) is the setpoint signal.
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.

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
There is a device called a radar detector, but it will only detect a radar signal, not police in general.
demodulator circuit is a circuit which is used for remove all high frequency components from modulated signal.
The 1N34 is a germanium signal diode, so it would be used as a detector/mixer in a.m. reception for example.
A crystal receiver does not run on electricity. It is simply powered by the radio waves it is receiving. A large antenna is used to receive the signal and moves the signal to the crystal detector or diode.
