For example, the peak at 20 MHz in the spectrum is caused by the parasitic oscillation due to the output capacitance of the MOSFET and the leakage inductance of the transformer.
Through discussing the samples of ac signal, the basic method to solve spectrumleakage is pointed out, which is to guarantee the same pace between signal frequency and sampling frequency.
通过对交流电信号采样的讨论,指出解决频谱泄漏的问题的基本方法是保证信号频率与采样频率同步。
