Sampling sine wave

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. WebSep 1, 2024 · As some of my previous posts, I'm trying to find the RMS of sine wave during the first cycle, but I still have some questions as for the sampling frequency. Let's say I choose a sampling frequency of 1 kHz. That's one sample per millisecond. For a 50 Hz signal: 20 ms/1 ms = 20 samples per cycle.

Shannon-Nyquist theorem reconstruct 1Hz sine wave from 2 …

WebAliasing occurs when the sampling rate is below the highest frequency in the input, f h. For the first sine function above this is any frequency below 100 Hz. The aliased signal reconstructed will be the difference between the input frequency and the sampling rate. If f s is 80 Hz for the 100 Hz sine wave the resulting aliased signal will be 20 Hz. WebAlex Lucas Kolbe Heeralal Figure 3 displays the work in the beginning of the second part of the lab. This sine wave has a 5v Peak-to-peak in amplitude, and a frequency of 20 MHz.

WebIQ sampling is more easily understood by using the transmitter’s point of view, i.e., considering the task of transmitting an RF signal through the air. We want to send a single sine wave at a certain phase, which can be done by sending the sum of a sin() and cos() with a phase of 0, because of the trig identity: . Let’s say x(t) is our ...

WebThe true shape of the waveform is not evident because the sampling speed is too slow. Most clearly, we see that if we sample at 1/2 the frequency of the monitored waveform, … WebAfter crossing the Nyquist Frequency, the sampled signal becomes a valid representation for not only the actual input wave (blue), but also a new sine wave (grey) which begins to decrease in frequency. Figure 1. Crossing the Nyquist Frequency. If we don’t limit the frequency of the input signal, and instead allow it to travel over the Nyquist ...

WebFeb 28, 2024 · Sampling a sine wave. 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. WebMay 22, 2024 · The sine wave is the simplest wave that may be created.
