A conventional voice radio cannot transnit data directly. Data digital voltage levels must be converted to audio using a device called a modulator, whichapplies the audio to the transmitter.
conversely,at the receiver,a demodulator converts audio back to digital voltage levels.
RF-5000 radios=>(build in)Highspeed modems,,,,,, which have Modfulator and demodullator(which permit the radios to operate with either voice or data inputs)
on the other side FSK(Frequency shift keying) only encoded binary data(0s and 1s).....
This case, Fsk is not suitable for high speed modems..............

What is use of frequency shift keying?
in point to point millitary communications , earlier telephone modems etc....
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.
What are the advantages of frequency shift keying?
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 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 is fsk in communication?
fsk is nothing but frequency shift keying which is used in low speed modems.....
In telegraphy how you are using frequency shift keying?
Like in modems, you make digital zeros one frequency and digital ones another frequency.

The amount of frequency shift during modulation is called?
Frequency shift keying in digital communication and Frequency modulation in analog communication..........
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.
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
What modulation does bluetooth use?
It uses GFSK (Gaussian Frequency Shift Keying) modulation technique.
What is block diagram of frequency shift keying modulation?
Block digram of fsk is the representation of fsk modulation
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.
What does fsk stand for?
FSK stands for Frequency Shift Keying, a method used in communication systems to encode information by varying the frequency of a carrier signal.
What is amplitude shift keying modulation?
micxingthe between the phasr and frepaancy shift keying
