as we know that for AM generation we use non linear resistances i.e. those in which current doesn`t vary linearly with applied voltage ;so here voltage is applied at the gate terminal let us say v(v1+v2 or v1-v2) then current will be given as like taken the general form for non linear resistance ....

AM-DSB-SC signal which detector is used?
WE CAN use the balanced modulator & also the double balanced modulator(DBM) THANKS. ASMA
How is balanced modulator different from diode bridge modulator?
A diode bridge modulator is one kind of balanced modulator.
Why balanced modulator is called balanced modulator?
the output from a balanced modulator consists of modulating freq also. this can be eliminated in a diode modulator by adding two more diodes, making a diode ring. therefore called ring modulator

What does a balanced modulator produce?
Please answerin the case of communication , a balanced modulator is used to suppress the carrier from a conventional amplitude modulated signal
How does a balanced ring modulator work?
a balanced modulator can use any non linear device which has a response of the form:- i=a+ bv + cv2 +..... it generally utilises a push pull FET circuit or a pair of identical diodes. the modulating voltage is tapped in between and with RF in series is fed to both source of FET. the gate of both FET gets AF and RF, AF tapped from either side of secondary coil makes it 180 deg out of phase. the drain outcome is added by which the phase opp carrier cancells leaving sidebands and modulating freq, which also can be filtered with tuned secondary at load.
Could a balanced modulator be used as a synchronous detector?
yes
Why you use FET?
FET's improve the switching frequency from KHZ to MHZ.. FET can be used as temperature sensor.. and mosfet is used as a switch..
Block diagram of amplitude modulation?
The basic block diagram consists of a modulator which may be a product modulator or a balanced modulator. The audio input signal is fed to the input of the modulator and there it is being multiplied by the carrier signal which is generated by using a oscillator. This block diagram in its crude form is given by:
Where is the modulator valve on a 2000 Chrysler?
Chrysler does not use modulator valves.
Where is the shift modulator on a 1996 Chrysler located?
Chrysler does not use modulator valves.
Which transistor is used in internal structure of LM 1496 balanced modulator demodulator IC?
A 2N3904 is the one in this package.
