Suppose we sample an 8 kHz sine wave at the commonly used rate of 48 kHz. The conditions of the sampling theorem are met since the sample rate is well above twice the maximum (and in this case only) frequency of the signal. Figure 1 shows one period of this sine wave with the sample points marked as red circles.

The signal source was from a high-quality sine wave generator from a different manufacturer. Soon a "beat" in the waveform display was observed near a certain single frequency on the signal generator (Figure 1). WebJun 30, 2024 · Lets say I want to set the minimal sampling rate to reconstruct a 1Hz sine wave, according to the Nyquist-Shannon theorem that states that the maximum recoverable frequency is Fs/2 i.e. we must sample the signal 2 times the maximum frequency. It seems obvious that the limit is a sampling frequency of 2Hz. mems wafer foundries
