Webb14 mars 2024 · In the general formula, B is related to the period by P = 2π B . If B > 1, then the period is less than 2π and the function undergoes a horizontal compression, whereas if B < 1, then the period is greater than 2π and the function undergoes a horizontal stretch. For example, f(x) = sin(x), B = 1, so the period is 2π ,which we knew. Webb27 mars 2015 · The "standard" form you believe you have is in fact a low-pass 2nd order filter.
