fsk and psk
fsk is nothing but frequency shift keying which is used in low speed modems.....
Block digram of fsk is the representation of fsk modulation
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.
required larger bandwidth
FSK stands for Frequency Shift Keying, a method used in communication systems to encode information by varying the frequency of a carrier signal.
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

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.
FSK, or Frequency Shift Keying, is a modulation technique that involves shifting the frequency of a carrier signal to transmit binary data. TSSB may refer to "The Stock Swing Band," which could be a musical group or band specializing in swing music. It is unclear what connection or context there is between FSK and TSSB in this case.
An FSK Modulator is much the same as a GFSK Modulator ,but GFSK uses a Gaussian filter as well. In a GFSK modulator everything is the same as a FSK modulator except that before the baseband pulses (-1, 1) go into the FSK modulator, it is passed through a gaussian filter to make the pulse smoother so to limit its spectral width.
The three main types of shift keying are Amplitude Shift Keying (ASK), Frequency Shift Keying (FSK), and Phase Shift Keying (PSK). ASK encodes data by varying the amplitude of the carrier signal, FSK uses different frequencies to represent data bits, and PSK changes the phase of the carrier wave to convey information. Each type has its own advantages and applications in digital communication systems.
