Method and apparatus for digital shaping of a digital data stream |
摘要 |
Digital method and apparatus for generation of a digital data stream with the bit transitions shaped to reduce splatter, and minimize droop and overshoot in a radio communications system utilizing digital coded squelch. A codeword digital data stream, in digitized form, is shaped so that the bit transitions have the form of a portion of a sine waveform and then is applied to a D/A converter. A simple filter follows the D/A converter to attenuate sampling noise.
