Abstract

The present invention relates to a method and system that emulates a desired waveform by producing a time profile of the desired waveform, which is characterized by a plurality of sample values, and generating a plurality of RF waveforms, each RF waveform of the plurality of RF waveforms having a polarity and scaled energy based on a corresponding one of the plurality of sample values, to produce an aggregate RF energy having spectral characteristics that approximate the spectral characteristics of the desired waveform.

Claims

1. A method of emulating a desired waveform, comprising:

producing a time profile of said desired waveform characterized by a plurality of sample values;

generating a plurality of RF waveforms, each RF waveform of said plurality of RF waveforms having energy scaled in accordance with a corresponding one of the plurality of sample values of said time profile.
