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
The amount of frequency shift during modulation is called?
Frequency shift keying in digital communication and Frequency modulation in analog communication..........
What are three main types of shift keying?
The three main types of shift keying are Amplitude Shift Keying (ASK), Frequency Shift Keying (FSK), and Phase Shift Keying (PSK). ASK encodes data by varying the amplitude of the carrier signal, FSK uses different frequencies to represent data bits, and PSK changes the phase of the carrier wave to convey information. Each type has its own advantages and applications in digital communication systems.
Which signaling systems would you recommend for a situation in which bandwidth is limited and noise interference is a consideration?
Phase shift keying Quadrature shift keying
What Type of modulation used in GSM?
The modulation used in GSM is Guassian minimum-shift keying (GMSK), a kind of continuous-phase frequency shift keying. In GMSK, the signal to be modulated onto the carrier is first smoothed with a Guassian low-pass filter prior to being fed to a frequency modulator, which greatly reduces the interference to neighboring channels (adjacent channel interference).

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.

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 bpsk circuit?

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
