A Modulated-Frequency System of Telemeterings
Transactions of the American Institute of Electrical Engineers, 1945WITH today's centralized control and supervision of power systems, it is essential that the man at the controls knows what is going on at all outlying stations and interconnection points. Telemetering equipment keeps him informed of load changes, transfer of power from one system to another, variations in voltage, and all other values that are ...

Pitch of Frequency-Modulated Sinusoids
The Journal of the Acoustical Society of America, 1969The pitch elicited by 300-, 1000-, and 3000-Hz sinusoids frequency modulated by 20, 200-, and 2000-Hz sinusoids (the latter for the 3000-Hz carrier frequency only) was investigated at 20 and 50 dB SL. The frequency deviation of the carrier frequency was ± 100 Hz for all stimulus conditions. Five normal-hearing listeners matched unmodulated sinusoids in

Orthogonal Modes of Frequency Modulation and the Sturm–Liouville Frequency Modulation Model
IEEE Transactions on Signal Processing, 2012Sinusoidal signals and complex exponentials play a critical role in LTI system theory in that they are eigenfunctions of the LTI convolution operator. While processing frequency-modulated (FM) waveforms using LTI systems, restrictive assumptions must be placed on the system so that a quasi-eigenfunction approximation holds.

Digital frequency synthesizer/modulator for continuous-phase modulations with slow frequency hopping
IEEE Transactions on Vehicular Technology, 1997This paper gives a description of a modulator for burst-by-burst carrier frequency hopping in TDMA systems. The architecture consists of a digital frequency synthesizer/modulator for a broad class of continuous phase modulations (CPMs) and a fast frequency settling RF synthesizer consisting of one phase-locked-loop (PLL). The performance of the digital
