- How does sinc interpolation work? - Mathematics Stack Exchange
Convolution with sinc pulses What we want to do to reconstruct the signal is a convolution between the samples and scaled and shifted versions of sinc This technique is known as Whittaker–Shannon interpolation: " This is equivalent to filtering the impulse train with an ideal (brick-wall) low-pass filter with gain of 1 (or 0 dB) in the passband
- convolution of gaussian and sinc function - Mathematics Stack Exchange
The convolution of a sinc and a gaussian is the Fourier transform of the product of a rect and a gaussian which is a truncated gaussian Maybe looking at the problem in the transform domain might be useful
- If $cos (A-B)+cos (B-C)+cos (C-A)=\frac {-3} {2}$, prove that $cosA . . .
Continuing from where we left off, we have that $$ 2 (\cos a \cos b + \sin a \sin b + \cos b \cos c + \sin b \sin c + \cos c \cos a + \sin c \sin a) + 3 = 0 $$ Now we write $3$ as $ (\cos^2 a + \sin^2 a) + (\cos^2 b + \sin^2 b) + (\cos^2 c + \sin^2 c) $ and substitute this in We then make use of the identity $$ (x + y + z)^2 = x^2 + y^2 + z^2 + 2 (xy + yz + zx) $$ to obtain that $$ (\cos a
