Abstract
The pulse-shaping look-up table with transient suppression ( ) avoids hard turn-on and turn-off transients by modifying word segments of initial and final digital words during transmission of a digital data sequence. A controller ( ) sends a mode signal and a digital data sequence to the pulse-shaping look-up table with transient suppression ( ). A mode buffer and command block ( ) uses the mode signal to control the creation of initial and final digital words created by a data buffer and control block ( ) from the digital data sequence. The digital words are used by a look-up table ( ) to create a sampled digital output waveform sequence. The pulse-shaping look-up table with transient suppression ( ) provides an accurate output waveform sequence with reduced spectral emissions even during start-up and shut-down of digital data transmissions.
