Abstract: A digital noise reduction for a radio frequency receiver communication systems that is field programmable to function with a large variety of signaling schemes or waveforms. The noise reduction arrangement includes circuits to convert the mulit bit digital signal (including noise impulses therein) into logarithmic form and uses exponential averaging to determine the presence of noise and the magnitude thereof. Various threshold circuits, the exponential averaging circuits and an exponential decay circuit are responsive to digital commands to set the thresholds for noise detection and control when the noise should be blanked and the duration of blanking.

Abstract: A decoder for Trellis encoded modulated signals. The decoder utilizes a modified Viterbi algorithm. The algorithm includes the use of two look-up tables. The look-up tables contain information regarding the current symbol, previous symbol and previous to previous symbol which can bring the trellis to the given state. The symbol information contained within these tables is indexed into the appropriate branch metric values and the path metric for the Viterbi algorithm is computed. The tables can be used effectively with the branch metric in either polar or rectangular form.

Abstract: Particle compositions are described comprising certain metal halides in combination with a strengthening agent. The addition of the strengthening agent to a metal halide particle increases the particle's strength thereby reducing breakage on impact and during handling. When used as a vaporizable metal halide fill in discharge lamps, the particle strength is increased without significantly altering the spectral and electrical characteristics of the lamp. Methods of making the particles and arc tube containing the particles are also disclosed.

Abstract: A system and method for controlling the frequency of a signal being transmitted wherein the frequency of the signal received at the transmitter site is error corrected before being broadcast. The error in the frequency may be developed and applied to the intermediate frequency upconversion and/or the channel upconversion to reduce or eliminate the effects of the error. In the system and method, a pilot frequency signal can be added to the signal to be broadcast after the signal to be broadcast has been shaped and filtered.

Abstract: A dimming system and method suitable for any type of magnetic ballast operating a gaseous discharge lamp. The dimming system operates to selectively vary the number of turns of the ballast winding in operative connection with the lamp to thereby effect a change in the impedance of the ballast, the power provided to the lamp, and ultimately the brightness of the lamp. The system may be operated such that the brightness of the lamp is selected responsive to the detection of an external stimulus such as motion or sound within the space to be illuminated.
