FAQs about Important Question of Advanced Communication for ESE Mains

  • Modulation is essential in communication systems as it enables the transmission of information over long distances. It involves the process of encoding the information onto a carrier signal, which allows the signal to be efficiently transmitted through a medium.

  • Analog modulation techniques involve varying the amplitude, frequency, or phase of the carrier signal in proportion to the information signal. It is used for transmitting continuous, analogue signals. Digital modulation, on the other hand, involves encoding discrete digital information onto the carrier signal using techniques such as amplitude-shift keying (ASK), frequency-shift keying (FSK), or phase-shift keying (PSK). Digital modulation is employed for transmitting discrete, digital signals.

  • Signal processing in communication systems involves various operations such as filtering, amplification, and modulation/demodulation. The key principles include analogue-to-digital conversion, digital-to-analogue conversion, noise reduction techniques, equalization, and error correction.

  • Multiplexing is the technique of combining multiple signals onto a single transmission channel. It allows for the simultaneous transmission of several signals, maximizing the utilization of the channel's capacity. Multiplexing can be achieved through methods like frequency division multiplexing (FDM), time division multiplexing (TDM), and wavelength division multiplexing (WDM).

  • Error control mechanisms in communication systems aim to detect and correct errors that occur during transmission. Some common techniques include parity checking, cyclic redundancy check (CRC), and forward error correction (FEC). Parity checking is simple but can only detect single-bit errors.
