Frequency-shift keying (FSK). This forces compromises in the design of the receiver frequency discriminator, which must accept variable deviation of say 5 to 10 kHz while the center frequency may change 30 kHz. Thus, the performance of FSK SAW devices is not likely to realize the advantages over ASK that are expected, and indeed FSK is not often used with SAWs., Ask Applications creates leading desktop applications, browser extensions, and software.

A digital modulation technique that transmits data by varying the phase of the carrier wave according to the digital modulating signal, is called Phase Shift Keying (PSK). The easiest form of PSK is BPSK i.e., binary phase shift keying. Phase Shift Keying (PSK) is the digital modulation technique in which the phase of the carrier signal is changed by varying the sine and cosine inputs at a particular time. PSK technique is widely used for wireless LANs, bio-metric, contactless operations, along with RFID and Bluetooth communications.

Comparing PSK and FSK-based digital modulations – Part 1 Most digital radio modulation types are based on either Phase Shift Keying (PSK) or Frequency Shift Keying (FSK). Tait Principal Engineer Ian Graham is often asked about their relative advantages and disadvantages, so in this article he sets out to explore the subject. One of the disadvantages of ASK, compared with FSK and PSK, for example, is that it has not got a constant envelope. This makes its processing (eg, power amplification) more difficult, since linearity becomes an important factor. However, it does make for ease of demodulation with an envelope detector. Intro to Bandwidth Modification . As already indicated, the sharp discontinuities in the ASK
