"A Practical Step Forward Toward Software-Defined Radio Transmitters". .. ^ Bureau of Standards 1922, pp.415416 ^ Little 1921, p.125 ^ Kennedy & Davis 1992, pp.549550 . Minimum frequency-shift keying or minimum-shift keying (MSK) is a particular spectrally efficient form of coherent FSK. References[edit]. AFSK is also used in the United States Emergency Alert System to transmit warning information[citation needed]. Revised to April 24, 1921.

The elimination of discontinuities in the phase (and therefore elimination of sudden changes in amplitude) reduces sideband power, reducing interference with neighboring channels. (1925), Radio: Beam and Broadcast, London: Ernest Benn Limited . ^ Steve Ford. p. (1992).

Retrieved 27 May 2015. The simplest FSK is binary FSK (BFSK). nRF24LU1 Preliminary Product Specification v1.2 ^ Bhagwat, Pravin (10 May 2005). For basic data rate Bluetooth the minimum deviation is 115kHz. Main article: Gaussian minimum shift keying.


Reference implementations of FSK modems exist and are documented in detail.[3] The demodulation of a binary FSK signal can be done using the Goertzel algorithm very efficiently, even on low-power microcontrollers.[4]. 2002. Little, D. Dots and dashes were replaced with different tones of equal length.[10] The intent was to minimize transmission time. See also[edit]. FSK is commonly used[citation needed] in Caller ID and remote metering applications: see FSK standards for use in Caller ID and remote metering for more details. 74309d7132
