摘要： A digital wavetable audio synthesizer is described. The synthesizer can generate up to 32 high-quality audio digital signals or voices, including delay-based effects, at either a 44.1 KHz sample rate or at sample rates compatible with a prior art wavetable synthesizer. The synthesizer includes an address generator which has several modes of addressing wavetable data. The address generator's addressing rate controls the pitch of the synthesizer's output signal. The synthesizer performs a 10-bit interpolation, using the wavetable data addressed by the address generator, to interpolate additional data samples. When the address generator loops through a block of data, the signal path interpolates between the data at the end and start addresses of the block of data to prevent discontinuities in the generated signal. A synthesizer volume generator, which has several modes of controlling the volume, adds envelope, right offset, left offset, and effects volume to the data. The data can be placed in one of sixteen fixed stereo pan positions, or left and right offsets can be programmed to place the data anywhere in the stereo field. The left and right offset values can also be programmed to control the overall volume. Zipper noise is prevented by controlling the volume increment. A synthesizer LFO generator can add LFO variation to: (i) the wavetable data addressing rate, for creating a vibrato effect; and (ii) a voice's volume, for creating a tremolo effect. Generated data to be output from the synthesizer is stored in left and right accumulators. However, when creating delay-based effects, data is stored in one of several effects accumulators. This data is then written to a wavetable. The difference between the wavetable write and read addresses for this data provides a delay for echo and reverb effects. LFO variations added to the read address create chorus and flange effects. The volume of the delay-based effects data can be attenuated to provide volume decay for an echo effect. After the delay-based effects

摘要： A lighting system includes one or more methods and systems to control the color spectrum of a lamp in response to both temperature and dim levels. In at least one embodiment, the lighting system includes a controller to control a correlated color temperature (CCT) and intensity of the lamp by independently adjusting currents to electronic light sources based on a dim level of the lighting system and temperature of the lighting system. The controller controls a first current to a first set of LEDs and a second current to a second set of LEDs. The control of the first current by the controller is jointly dependent on a dim level and temperature in the lighting system. In at least one embodiment, the control of the second current is dependent on the dim level or the dim level and temperature.

摘要： A system provides I and Q baseband analog modulation signals for use in GMSK modulation responsive to serial bits of digital data. The I baseband modulation signal is represented by I(t)=cos [2.pi.f.sub.m .intg.g(t)dt] and the Q baseband modulation signal is represented by Q(t)=sin [2.pi.f.sub.m .intg.g(t)dt], wherein f.sub.m is the modulating frequency and g(t) is a filtered version of the serial bits of digital data. The system includes an input for receiving the serial bits of digital data, a memory including addressable memory locations for storing data representing the waveform amplitudes of the I and Q modulation baseband analog signals, and an address generator for addressing selected ones of the memory locations responsive to the serial bits of digital data. The system further includes digital to analog converters coupled to the memory for receiving the data stored at the memory locations addressed by the address generator and for converting the data to the I and Q modulation baseband analog signals.
