What is spectrum of FSK?

FSK, in the most basic case, represents a 1 (a mark) by one frequency and a 0 (a space) by another. These frequencies lie within the bandwidth of the transmission channel. On a V. 21, 300 bps, full-duplex modem the originator modem uses the frequency 980 Hz to represent a mark and 1180 Hz a space.

What does the FSK signal represent?

Frequency Shift Keying (FSK) is a method of transmitting digital data by shifting the frequency of a carrier signal to represent binary 1s and 0s.

What is the bandwidth of an FSK signal?

The bandwidth of the periodic FSK signal is then 2f + 2B, with B the bandwidth of the baseband signal. form. In order for envelope detection to be successful, the peaks in the frequency domain at ωc − ω and ωc + ω must be widely separated with respect to the bandwidth of the baseband signal.

How many frequencies are used in FSK?

In the simplest form of FSK signaling, digital data is transmitted using one of two frequencies, whereby one frequency is used to transmit a 1 and the other frequency to transmit a 0.
