→Investigating the filter response
|
We want to find how much the filtering affects the noise of the X and Y channels. To do that we take two measurements:
====
===== X noise (time domain) ====
===== X noise (frequency domain) ====
===== Y noise (time domain) ====
===== Y noise (frequency domain) ====
==== Known signal ====
Mike suggested that we apply a known signal to the FPGA input to measure the noise produced by the processing VI.
We are sending a 0.1V 10 Hz AC signal into the FPGA from a frequency synthesizer DS345.
===== X noise (time domain) ====
===== X noise (frequency domain) ====
===== Y signal (time domain) ====
===== Y signal (frequency domain) ====
