What is the difference between FSK and MFSK?
Multiple frequency-shift keying (MFSK) is a variation of frequency-shift keying (FSK) that uses more than two frequencies.
What is the difference between FSK and GFSK?
First of all, GFSK modulation is a much cleaner signal than FSK. This is because GFSK process filters out spurious to a much narrower transmission bandwidth than FSK. But in addition to that, we are now transmitting at 76.8Kbps which has a much wider bandwidth than 4.8Kbps we used before.
What is the difference between amplitude shift keying and frequency-shift keying FSK?
ASK refers to a type of amplitude modulation that assigns bit values to discrete amplitude levels. The carrier signal is then modulated among the members of a set of discrete values to transmit information. FSK refers to a type of frequency modulation that assigns bit values to discrete frequency levels.
What is the difference between FM and FSK?
FSK might be termed a special case of FM. In the more general FM, the modulating waveform is typically a continuously variable audio signal, like speech or music. In FSK, the carrier frequency switches between discrete values, typically (but not necessarily) just two values. FSK is essentially FM with digital signals.
