filtering noise off simulate signal express vi

[kwaris]

Hi,

This may be rather simple but I am stuck.

For simulation purposes, I want to display a sine wave signal carrying noise and same signal without noise on same waveform chart.

I used express palletes(simulate signal, filter) but with these palletes I guess filter is filtering depending upon weither high pass or low pass filter is chosen and not the noise signal. Ideally, I should get noise free sine wave shown in display signal when simulate signal is double-clicked provided add noise is not checked.

I wonder if I could get both these signals (sine + noise , sine only) on the same waveform chart.

Many thanks in advance

From what I understand you want, it would be as simple as the code below.

Hi

Thanks for reply, I had done the same. I wonder why on waveform chart the filtered signal is not perfect sine wave. Is it the best we get by simulation?

Also, I had chosen low past filter with cut off frequency 50Hz!

Thanks and Regards
