FSK is not always used for high-speed data communications, since it is far less efficient in both power and bandwidth than most other modulation modes. In addition to its simplicity, however, FSK has the advantage that encoded signals will pass through AC-coupled links, including most equipment originally designed to carry music or speech.

What is fsk in communication?
fsk is nothing but frequency shift keying which is used in low speed modems.....
Compear fsk and psk?
fsk and psk
FSK MODEMs use variation in what parameter to represent data?
Frequency. FSK means Frequency Shift Keying.FSK MODEMs use 4 frequencies at the low end of the audio range:1070 Hz (Space - originating MODEM)1270 Hz (Mark - originating MODEM)2025 Hz (Space - answering MODEM)2225 Hz (Mark - answering MODEM)These frequencies were selected by AT&T to all fit in the 3000 Hz bandwidth of a standard long distance voice telephone line and allow both sides to be sending data at the same time without interfering with each other.
What is block diagram of frequency shift keying modulation?
Block digram of fsk is the representation of fsk modulation
What is FSK in telecommunication?
FSK stands for Frequency Shift Keying. It allows for voice and data to be digitized and transferred over analog lines. There is a maximum transfer rate of FSK data at 1.6 Mbps.
Why fsk does not used for high speed mode?
Frequency Shift Keying (FSK) is generally not used for high-speed data transmission because it requires a larger bandwidth compared to other modulation techniques like Phase Shift Keying (PSK) or Quadrature Amplitude Modulation (QAM). The inherent nature of FSK, which relies on shifting between discrete frequencies, can limit the data rate and increase susceptibility to noise and interference. Additionally, as data rates increase, the frequency separation needed for reliable detection may become impractical, leading to reduced efficiency and performance in high-speed applications.
Who invented the first PC modem and when?
Digital modems developed from the need to transmit data for North American air defense during the 1950s. Modems were used to communicate data over the public switched telephone network or PSTN. Analog telephone circuits can only transmit signals that are within the frequency range of voice communication. A modem sends and recieves data between two computers. Modem stands for modulate/demodulate.In 1962, the first commercial modem was manufactured - the Bell 103 by AT&T. The Bell 103 was also the first modem with full-duplex transmission, frequency-shift keying or FSK, and had a speed of 300 bits per second or 300 bauds.The 56K modem was invented by Dr. Brent Townshend in 1996.
What are the disadvantages of fsk?
required larger bandwidth
What does fsk stand for?
FSK stands for Frequency Shift Keying, a method used in communication systems to encode information by varying the frequency of a carrier signal.
What is the advantage and disadvantage of fsk fsk and psk modulation?
advantages of fsk arelow noise,since amplitude is constantpower requirement is constantoperates in virtually any wires availablehigh data rateused in long distance communicationeasy to decodegood sensitivity
What are the applications of fsk?
point to point military communication
What musician has FSK as initials?
Francis Scott Key
