What is a demodulator?
The process of separating the original information or SIGNAL from the MODULATED CARRIER. In the case of AMPLITUDE or FREQUENCY MODULATION it involves a device, called a demodulator or detector, which produces a signal corresponding to the instantaneous changes in amplitude or frequency, respectively. This signal corresponds to the original modulating signal
Is there any special IC for amplitude modulation?
MC1496-AM modulator and demodulator chip -- shark
Why we use band pass filter in binary phase shift keying receiver or not low pass filter?
The bpsk receiver requires a particular band of frequencies to be passed to generate the required carrier which is further divided and then given to the demodulator. So the basic use of the bpf is to bandlimit the signal generated by the square law device and attenuate any dc levels otherwise. Lpf would simply allow all low frequencies to pass, which is not desired.
Converting digital computer signals to audible analog tones is known as?
Modulating. The word modem comes from Modulator/Demodulator
Discussion about amplitude demodulator?
A modulator modulates the carrier frequency, while a demodulator detects the modulation on the carrier wave and recovers the original lower frequency waveform at the destination. For many years the modulated carrier wave was converted to a radio signal. Now it is often an electrical signal which is sent down a teleohone line; the information is usually a set of pulses going between computers. When computers are connected to each other in a two-way conversation, the MOdulator and DEModulator are combined into a single device called a MODEM.
What is the more common abbreviation for a modulator-demodulator?
demodulator
What two words were combined to make up the modem?
modem (modulator + demodulator)
What does a modulator-demodulator stand for?
Modulator-Demodulator stands for modem
How demodulator works?
a demodulator sole function is to restore the original modulating signal. it works by removing the Carrier
What modem does?
Modulator/Demodulator
What are the fetures of modem?
Modulator and Demodulator
Am demodulator diode detector circuit?
demodulator circuit is a circuit which is used for remove all high frequency components from modulated signal.
What is the full meaning of moderm?
modulator demodulator
What is the full meaning of the abbreviation modem?
Modem = modulator-demodulator, and is a tool for tweaking an analog signal so that it can be used in a digital device.
What is MODEM short for?
MODEM stands for 'Modulator-Demodulator'.
What law states that the brightness of a star vaies inversely as the square of the distance from the stars?
The law is called The Inverse Square Law .
Is the word modem an acronym for modulate-demodulate?
modulator-demodulator
