摘要：
A waveform generation scheme based on complex filter and frequency-time mapping is proposed. In the experiment, a programmable processor was used for the complex filter. The shape of the spectrum is controlled by the amplitude frequency response, and the second order phase is controlled by the phase frequency response to realize frequency-time mapping. In experiment, rectangular pulse, sawtooth pulse and comb lines are realized by adjusting the complex filter. The influence of dispersion and spectral 3dB bandwidth on the time domain waveform is also analyzed. The proposed waveform generation is dynamically adjustable due to the dispersion is continuously tunable.
