Any device that performs signal conversion is _________.
Any device that performs signal conversion is _________.
The correct option is B Modulator
Any device that performs signal conversion is Modulator.
A modulator is a device that performs modulation. A
demodulator (sometimes detector or demod) is a device that performs
demodulation, the inverse of modulation. A modem (from modulator–demodulator)
can perform both operations.
A demodulator is a circuit that is used in amplitude
modulation and frequency modulation receivers in order to separate the
information that was modulated onto the carrier from the carrier itself. A
demodulator is the analog part of the modulator.
Modulation allows us to send a signal over a bandpass
frequency range. If every signal gets its own frequency range, then we can
transmit multiple signals simultaneously over a single channel, all using
different frequency ranges. Another reason to modulate a signal is to allow the
use of a smaller antenna.
