Pulse Signal Synthesis Scheme Based on Sub-Band Decomposition

A pulse signal generator is an essential tool in electronic testing, which can generate pulse signals with adjustable amplitude, frequency, edge time, and pulse width. Ultra-low duty cycle pulse signals have extremely narrow pulse widths and usually have swift edge times, making them have ultra-wideband signals' characteristics. Such a situation undoubtedly puts higher requirements on the performance indicators of electronic measurement systems. Many existing integrated circuit processes limit the current electronic system and cannot condition and synthesize ultra-low duty cycle pulse signals. In this paper, we propose a pulse signal synthesis method based on the sub-band decomposition of pulse waveform to address the problem that the performance of devices in the signal conditioning channel cannot meet the conditioning of high-speed pulse signals, which effectively reduces the required bandwidth of the pulse waveform for electronic devices, fills the deficiency of the waveform conditioning system in the ultra-wide bandwidth problem, and minimizes the attenuation of the waveform frequency components. It has been shown experimentally that the pulse signal synthesis scheme based on sub-band decomposition is highly accurate.
