Sampled sine wave
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 ...

Read … Webbe your one period of sampled signal (look up table samples) where w k (being between 0 and π) is the discrete time frequency of the generic set of samples. And let your DAC output period be T s then the produced output sine wave will have the frequency of: f s i n e = ω k 2 π T s. Again by adjusting T s or ω k you can control this frequency.
WebThe question immediately arises: can every sine wave be reconstructed from its samples? The answer, unfortunately, is \no." Review Sampling Aliasing Aliased Frequency Aliased Phase Summary Example Can every sine wave be reconstructed from its samples? For example, two signals x 1(t) and x WebThis means we can capture and reconstruct the original sine wave’s frequency with an audio sample rate at least twice its frequency, a rate called the Nyquist rate. Conversely, a system can capture and recreate …
