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
Francis Scott Key
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.
-> frequency shift keying promotes long distance communication. ->it has high security. ->low noise ->efficiency is high. ->decoding of signal is easy.
frequency modulation, preferably.
