What is FSK modem?
Frequency-shift keying (FSK) is a method of transmitting digital signals using discrete signals. A modem converts the binary data from a computer to FSK for transmission over telephone lines, cables, optical fiber or wireless media.

Parameters ASK PSK
-------------------------------- -------------------------- ---------------------------
Complexity Simple Very complex
Error probability High Low
Performance in presence of noise Poor Better than FSK

What do you mean by PSK?
abbreviation for. phase shift keying: a digital data modulation system in which binary data signals switch the phase of a radio frequency carrier.
Which is better PSK or FSK?
PSK modulation techniques are in general better than FSK modulations in terms of bandwidth requirements or in other words PSK modulation schemes offer better bits/s/hz efficiency. However FSK modulation schemes are more power efficient i,e, offers better BER performance at a given S/N (signal-to-noise ratio).16 Jun 2007
What is the concept of FSK?
S. (Frequency Shift Keying) A simple digital modulation technique that uses two frequencies for 0 and 1. See frequency modulation. Frequency Shift Keying. FSK is a simple technique that uses two frequencies to represent 0 and 1.
Is FSK digital?
Frequency-shift keying (FSK) is a frequency modulation scheme in which digital information is transmitted through discrete frequency changes of a carrier signal. BFSK uses a pair of discrete frequencies to transmit binary (0s and 1s) information.
Is FSK a FM?
In telecommunications and signal processing, frequency modulation (FM) is the encoding of information in a carrier wave by varying the instantaneous frequency of the wave. This modulation technique is known as frequency-shift keying (FSK).
What is the difference between FSK and FM?
Frequency modulation (FM) is the encoding of information in a carrier wave by varying the instantaneous frequency of the wave. FSK is widely used in computer modems, such as fax modems, telephone caller ID systems, garage door openers, and other low-frequency transmissions. Radioteletype also uses FSK.
Is amplitude-shift keying analog or digital?
Amplitude-shift keying (ASK) is a form of amplitude modulation that represents digital data as variations in the amplitude of a carrier wave.
What are the advantages of ASK over FSK?
Advantages of ASK modulation ➨It offers high bandwidth efficiency. ➨It has simple receiver design. ➨ASK modulation can be used to transmit digital data over optical fiber. ➨ASK modulation and ASK demodulation processes are comparatively inexpensive.
What are the advantages of FSK and PSK over ASK?
Benefits or advantages of PSK ➨It carries data over RF signal more efficiently compare to other modulation types. Hence it is more power efficient modulation technique compare to ASK and FSK. ➨It is less susceptible to errors compare to ASK modulation and occupies same bandwidth as ASK.
What are the application of FSK?
Following are the typical applications of FSK modulation. It is used on voice grade lines for data rates upto 1200 bps. It is used for high frequency radio transmission from 3 to 30 MHz. It is also used in coaxial cable based LAN (Local Area Network) at higher frequencies.
