frequency-shift keying

[′frē·kwən·sē ‚shift ′kē·iŋ]
(communications)
A form of frequency modulation used especially in telegraph, data, and facsimile transmission, in which the modulating wave shifts the output frequency between predetermined values corresponding to the frequencies of correlated sources. Abbreviated FSK. Also known as frequency-shift modulation; frequency-shift transmission.

The solutions used simple modulation techniques like amplitude-shift keying (ASK) or frequency-shift keying (FSK).
Smartphones, microfluidics, low-power devices, 1-way valves, optical sensing, multiplexed assays, frequency-shift keying, and lyophilization are not new technologies.
Therefore, if the resonant frequency of the antenna is switched at a high rate, a fast frequency-shift keying (FSK) modulation can be directly realized.
Similarly, frequency-shift keying (FSK) transmits a "one" on one frequency and a "zero" on another frequency.
The MSK modulation format is a special case of binary frequency-shift keying (FSK) in which the selected modulation index is h = 0.5, which is the value that forces a phase change of [pm][pi]/2 on each bit interval.
Aktakom AWG-4151 universal generator can work not only with harmonic signals, but also has modulation opportunities and other special modes including: amplitude modulation (AM), frequency modulation (FM), phase modulation (FM), frequency-shift keying (FSK), and also operation in pulse width modulation (PWM), sweep mode, frequency and pulse bursts.
With the addition of only a few other peripheral components, the two ICs can be integrated to form a small, cost-effective transceiver capable of transmitting and receiving FM or frequency-shift keying (FSK) signals in the 860 to 965 MHz frequency range with input data rates up to 500 kbps.
The basic possibilities are amplitude-shift keying (ASKe, phase-shift keying (PSK) and frequency-shift keying (FSK).
