In FSK the output frequency is dependent on the input bit stream. Here 2 (for Binary FSK) different carrier frequencies are used and they are switched according to input bit stream. When input is at logic1 output is freq. f1 and when input at logic0 output is freq. f2, where f1 and f2 are different.

What is use of frequency shift keying?
in point to point millitary communications , earlier telephone modems etc....
What are the advantages of FSK?
-> frequency shift keying promotes long distance communication. ->it has high security. ->low noise ->efficiency is high. ->decoding of signal is easy.
What are the advantages and disadvantages of binary phase shift keying?
One advantage is more bandwidth. A disadvantage is that the transmitted power is lower.
Which type of modulation is used in TV transmission?
In television system for video transmission AM is used and for audio transmission FM is used....
What is bpsk circuit?
Binary (Bipolar) Phase Shift Keying.
Disadvantage of frequency shift key?
The disadvantage of frequency shift key is it requires high bandwidth. The advantages of it are that frequency shift keying promotes long distance communication, it has high security, low noise, efficiency is high, and decoding of signal is easy.
Why do you use envelope detection in an M-ary Frequency Shift Keying noncoherent Modulator?
Envelope detection is used in an M-ary Frequency Shift Keying noncoherent modular because LOs are not required. Moreover, an estimate of 1dB of more power compared to the Frequency Shift Keying coherent demodulation.
The amount of frequency shift during modulation is called?
Frequency shift keying in digital communication and Frequency modulation in analog communication..........
What are the advantages of phase shift keying?
The advantage of a binary phase-shift keying is that within a given bandwidth, modulation of higher orders allow to carry higher rates.
What is the difference between amlitude shift key and frequency shift key?
Amplitude shift keying changes the height/power of the transmitted signal without altering the frequency. Frequency shift keying changes the frequency of the transmission without altering the height/power of the transmitted signal. Morse code is an example of amplitude keying where the amplitude is 0 or 100%. RTTY teleprinter uses FSK with two frequencies and the codes that represent text characters are sent with patterns of the two frequencies.
What is the application of frequency shift keying?
amplitude shift keying is a form of modulation in digital signal that variation in the amplitude of carrier wave. application of ask: *used mainly for radio frequencies
In telegraphy how you are using frequency shift keying?
Like in modems, you make digital zeros one frequency and digital ones another frequency.
What are the advantages of binary phase-shift keying?
The advantage of a binary phase-shift keying is that within a given bandwidth, modulation of higher orders allow to carry higher rates.
What modulation does bluetooth use?
It uses GFSK (Gaussian Frequency Shift Keying) modulation technique.
What is fsk in communication?
fsk is nothing but frequency shift keying which is used in low speed modems.....
What is block diagram of frequency shift keying modulation?
Block digram of fsk is the representation of fsk modulation
What is use of frequency shift keying?
in point to point millitary communications , earlier telephone modems etc....
