Downsample Digital Waveform

[FrankBrown]

Hello,

Is there a way to downsample a digital waveform?

Thank you.

Do you mean to reduce the sampling rate such that the edges are still intact?

• For example, you generate a 1MHz clock signal at a 200MHz sampling rate - effective oversampled by 100x times
• When downsampled, it will become a 2MHz sampling rate and still retains the 1MHz clock signal

If my above statement is correct - then nope, no readily available tool

But there is digital compress and uncompress - this does not change the sampling rate but only reduces the memory footprint by discarding redundant cycles

@santo_13 - Thank you for pointing "Compress Digital.vi" to me.

It uses its knowledge of signal transitions to remove the duplicated rows and only keeps the transition values! this is great!! 

Thank you very much.
