有没有办法关闭Delta Sigma ADC的内部过滤器?

你好。我把它发布到PSoC设备编程论坛,但也许这是一个更好的地方来发布我的问题。因此,我在这里提出我的问题。

似乎ADC的内部滤波器阻止我对信号进行二次采样,即以比奈奎斯特低通要求低得多的频率进行采样。

  Hi. I posted this in the PSoC Device Programming forum, but maybe this was a better place to post my problem in. I am therefore reposting my question here.
    --
    It seems the internal filter of the ADC is preventing me from subsampling a signal, ie sampling at a much lower frequency than the Nyquist low-pass requirement.
    Is there any way to switch off the internal filters of the Delta Sigma ADC?

你好,
是否有任何特定的原因,你想采样信号的采样率小于奈奎斯特率?
干杯

  Hi,
     
    Is there any specific reason why you want to sample the signal with a sampling rate less than the Nyquist Rate?
     
    Cheers
