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 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.
In telegraphy how you are using frequency shift keying?
Like in modems, you make digital zeros one frequency and digital ones another frequency.
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....
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 is amplitude shift keying modulation?
micxingthe between the phasr and frepaancy shift keying
What does the acronym 'BPSK' mean?
The acronym "BPSK" stands for burst pulse shift keying. Burst pulse shift keying is the simplest form of phase shift keying or PSK known currently to exist.
What is the exact definition of differential phase shift keying?
differential phase-shift keying (′dif·ə′ren·chəl ′fāz ′shift ′kē·iŋ) (communications) Form of phase-shift keying in which the reference phase for a given keying interval is the phase of the signal during the preceding keying interval. Also known as differentially coherent phase-shift keying.Above retrieved from Answers.comViper1
