advantages of fsk are
- low noise,since amplitude is constant
- power requirement is constant
- operates in virtually any wires available
- high data rate
- used in long distance communication
- easy to decode
- good sensitivity

∙ 15y agoWe can do FSK using only two frequencies nothing else is required while in PSK we need to keep track of the change in the phase of the receiving signal.

What are modulation techniques in satellite communication?
frequency modulation, preferably.
Compear fsk and psk?
fsk and psk
Advantages of psk over fsk and ask?
PSK (Phase Shift Keying) is advantageous over FSK (Frequency Shift Keying) and ASK (Amplitude Shift Keying) because it provides higher data rates and better spectral efficiency. PSK is less susceptible to noise and interference since phase changes are more discernible than frequency or amplitude changes. PSK also allows for easier implementation in digital communication systems.
What is the advantage of qam over ask and psk?
PSK and QAM modulation have two advantages over ASK: *They are not as susceptible to noise. *Each signal change can represent more than one bit PSK Disadvantage more complex signal detection / recovery process, than in ASK and FSK QAM advantage: · data rate = 2 bits per bit-interval! · higher data rate than in PSK (2 bits per bit interval), while bandwidth occupancy remains the same • 4-PSK can easily be extended to 8-PSK, i.e. n-PSK • however, higher rate PSK schemes are limited by the ability of equipment to distinguish small differences in phase uses "two-dimensional" signaling • original information stream is split into two sequences that consist of odd and even symbols · PSK modulators are often designed using the QAM principle, but are not considered as QAM since the amplitude of the modulated carrier signal is constant. QAM is used extensively as a modulation scheme for digital telecommunication systems. Arbitrarily high spectral efficiencies can be achieved with QAM by setting a suitable constellation size, limited only by the noise level and linearity of the communications channel. · Noise immunity of QAM is very high. · QAM is best suitable for high bit rates. · Low error probability. · Baud rate is half the bit rate therefore more effective utilization of the available bandwidth of the transmission channel.

What is hybrid modulation?
—Analog digital hybrid modulation seeks the ways to eliminate the incoherent quantization noise component in digital communication, instead of conveniently making it minimal.
