in psk we need to keep track of the change in the phase of the receiving signal, in fsk we can using only 2 frequencies

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 dpsk over psk?
DPSK (Differential Phase Shift Keying) is more robust against phase fluctuations during transmission compared to PSK (Phase Shift Keying). It eliminates the need for a phase reference, making it more suitable for noisy channels. Additionally, DPSK can provide better error performance in certain scenarios compared to PSK.

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.
According to following constellation diagram if bit rate is 6400 bps what is the Baud Rate?
From the given constellation diagram determine whether its ASK, FSK, PSK or n-QAM. Then use the appropriate value of r to get Baud Rate = Bit Rate/r.

Why does your dsi ask you a security key is needed to connect to this access point enter the security key then tap ok and What is the security key?
The security key is the password for the wireless router. It'll show up if the wireless encryption is : WEP WPA-PSK (TKIP) WPA2-PSK(TKIP) WPA-PSK (AES) WPA2-PSK (AES).
Which signaling is used in telecom?
More information needed. Telecoms use FSK, PSK, and QAM, with A/D and D/A such as PCM, APCM, Delta and Delta-Sigma. They also use X.25, Frame Relay, ATM, SONET and TCP/IP.
