CYCLE-BY-CYCLE SYNCHRONOUS WAVEFORM SHAPING CIRCUITS BASED ON TIME-DOMAIN SUPERPOSITION AND CONVOLUTION

摘要

Cycle-by-cycle synchronous waveform shaping is provided for by filtering and combining of square and/or impulse shaped signals. Specifically, a plurality of first square shaped signals is generated and filtered using at least one first filter to produce at least one filtered signal. A plurality of second square shaped signals is generated and filtered using at least one second filter to produce at least one second filtered signal. The at least one first and at least one second filtered signals are combined to produce a continuous shaped waveform having a characteristic shape within each of a plurality of data periods defining a data rate. Alternatively, at least one impulse signal having a plurality of sinusoidal impulses each comprising a positive impulse and a negative impulse is generated. The at least one impulse signal is filtered using at least one filter to produce the continuous shaped waveform.
