Frequency shif keying
WebFrequency-Shift Keying (FSK) Modulation. You can configure the instrument to "shift" its output frequency between two preset values (called the "carrier frequency" and the … WebASK – Amplitude Shift Keying. The amplitude of the resultant output depends upon the input data whether it should be a zero level or a variation of positive and negative, depending upon the carrier frequency. FSK – Frequency Shift Keying. The frequency of the output signal will be either high or low, depending upon the input data applied.

Web3. FSK (Frequency Shift Keying) In FSK, bit ‘1’ and ‘0’, or symbols, are represented by different but unique frequencies of the carrier. The simplest form is BFSK (or 2-FSK), which has two frequencies to represent bit ‘1’ and ‘0’. Higher order forms include:- 4 … Frequency-shift keying (FSK) is a frequency modulation scheme in which digital information is encoded on a carrier signal by periodically shifting the frequency of the carrier between several discrete frequencies. The technology is used for communication systems such as telemetry, weather balloon … See more Reference implementations of FSK modems exist and are documented in detail. The demodulation of a binary FSK signal can be done using the Goertzel algorithm very efficiently, even on low-power … See more Multiple frequency-shift keying Continuous-phase frequency-shift keying In principle FSK can be implemented by using completely independent free-running oscillators, and switching between them at the beginning of each symbol period.
