Sampled sine wave
WebJul 24, 2024 · If a 90 Hz sine wave is sampled at 1,000 samples per second, the wave has an analog frequency of 0.09 of the sampling rate, represented by: f= 0.09 x1000. Eleven … WebThe following commands make a 256 point sine wave and measure its total harmonic distortion when sampled first on the points and then by jumping with a delta of 2.5 points …

WebFigure 1 shows a set of four continuous sine waves which are all being sampled at the same rate. You can adjust the sampling rate using the slider at the bottom of the visualization. Spend enough time with this visualization and you’ll notice some very strange properties of the sampling process. WebIf you aren’t already convinced that sampling is a tricky business, take a look at the following theorem. 1 The Sampled Sine Wave Theorem Given a sampling rate of SR hertz, and an integer k, A sine wave at a frequency of F is indistinguishable from a sine wave at a frequency of F + (k × SR) after sampling.

WebAfter quantizing a sampled sine wave, it plots the original and quantized signals. The plot contrasts the x 's that make up the sine curve with the dots that make up the quantized signal. The vertical coordinate of each dot is a value in the vector codebook.
WebA sine wave can be represented by the following equation: y ( t) = A s i n ( ω t + ϕ) where A is the amplitude of the wave, ω is the angular frequency, which specifies how many cycles occur in a second, in radians per second. ϕ is the phase of the signal. If T is the period of the wave, and f is the frequency of the wave, then ω has the ... WebDec 7, 2024 · The wave that is originally sampled must be sinusoidal. That’s fancy talk that means that we are indeed using waves and haven’t just drawn a random curvy line with …
WebSampled Waveforms. For demonstrations and explanations, we'll look at three closely related waveforms: y = sin(2 π t), a 1 cycle per second or 1 Hertz sine wave. y = sin(2 π t * …
