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..............

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.
