ASTEC UM 1286 UHF modulator, top cover taken off. An RF modulator (radio frequency modulator) is an electronic device used to convert signals from devices such as media players, VCRs and game consoles to a format that can be handled by a device designed to receive a modulated RF input, such as a radio or television receiver.
[2] [3] This results in a constant-modulus signal (constant envelope signal), which reduces problems caused by non-linear distortion. In addition to being viewed as related to OQPSK, MSK can also be viewed as a continuous-phase frequency-shift keyed ( CPFSK ) signal with a frequency separation of one-half the bit rate.

The Um physical layer is defined in the GSM 05.xx series of specifications, with the introduction and overview in GSM 05.01. For most channels, Um L1 transmits and receives 184-bit control frames or 260-bit vocoder frames over the radio interface in 148-bit bursts with one burst per timeslot.
Frequency deviation is used in FM radio to describe the difference between the minimum or maximum extent of a frequency modulated signal, and the nominal center or carrier frequency.
The new tables should be applicable now and in the future. The total scores using the new tables for the top world-class athletes should remain approximately the same (about 8500 points). As much as possible, the new tables should ensure that a specialist in one event cannot overcome top performances in the other events.
A placing table is a team ranking system used in sports competitions that feature multiple finals. It shares similarities with the better-known medal table found at most multi-sport events, but goes beyond the top three performers and assigns weighted scores to each athlete based on their overall final placing, then aggregates the scores of all athletes in a team to provide a final team standing.
An electro-optic modulator (EOM) is an optical device in which a signal-controlled element exhibiting an electro-optic effect is used to modulate a beam of light. The modulation may be imposed on the phase , frequency , amplitude , or polarization of the beam.
