Where is 3dB bandwidth from transfer function? the -3 dB frequency is at the frequency which results in half of the power as in the center …
WebThe -3dB point is also known as the "half power" point. In voltage it may not make not make tons of sense as to why we use ( 2 / 2 ), but lets look at an example of what it means in the sense of power. First off, P = V 2 / R, but lets assume R is a constant 1 Ω. Because of the constant 1ohm, we can remove it from the equation all together. WebAug 1, 2024 · A well known property of the Fourier transform is that a pulse in the time domain results in a sinc function, sin(x)/x, in the frequency domain.
