What are the two methods to demodulation?

Based on this nonlinearity, the demodulation methods can be broadly classified as methods using rectification (non-synchronous detection) and methods using mixing with a reference oscillator signal (synchronous detection).

Which of the following demodulator can be used for demodulating the signal?

Detailed Solution. MODEM: Modem stands for Modulator-demodulator. It converts the analog signals from the transmission wires into digital signals which can be read by the computer devices (modulation).

What is square law modulator?

(1) A square law device is one that produces an output voltage or current that is proportional to the square of its input voltage or current. Square law devices are mainly used in modulators and detectors. Example: The detector diode used in communication systems, FETs used in balanced modulator etc.

How do you demodulate over modulated signals?

In order to demodulate a double-modulated signal such as , at least two demodulators are necessary. Using the tandem technique, the in-phase or X-component of demodulated signal at the carrier frequency is internally routed to the second demodulator at sideband frequency.
