Sampling a sine wave in python

The sampling rate of the DSO is 160 GSa/s and my signal is 60 GHz. I need to find the phase difference between the two sine waves. Both are the same frequency. However, the sampling rate is not enough to accurately determine the phase. Is there any way to interpolate the measured signal to get a better sine wave and then calculate the phase ... Jun 16, 2021 · 2. Why is the amplitude changing throughout the signal. Because you are sampling it at oh so slightly less than c_freq/2. Your linspace call generates x points that are evenly spaced between 0 and 3, with a spacing between them of 3 * c_freq * 2 / (3 * c_freq * 2 + 1). This means that the phase that gets calculated is [ 0, π − ϵ, 2 π − 2 ... Aug 25, 2013 · The OP is trying to sample a single frequency sine wave for input to a Fourier transform.

Mar 02, 2014 · The output is delayed and fed back into the input. The output is the inverse of the input. This means that without the delay the circuit would do nothing at all. However, because there is a delay it oscillates making a sine wave. We can make a Python generator do very much the same thing: The 'NONE' and 'not compressed' just indicate that we are creating an uncompressed wavefile (nothing else is supported by the wave module at the time of writing).. Now the wavefile is ready for our audio data. 16 bit audio is encoded as a series of signed 16 bit integers.
