WebJan 27, 2024 · Take a simple sinewave with a frequency of 1 Hz and a duration of 1 second as shown in Figure 1. The signal has 128 samples and therefore a sampling rate of 128 samples per second. Notice that the signal ends just before 1.0 seconds. That is because our first sample is at t = 0.0 and we would actually need 129 samples to span t=0.0 to t=1.0.
