 % Repetitive Box filter to approx Gauss
 % Simple multipass, n/m approach, extended box filter
 Digital filters are implemented by convolving the input signal with a filter kernel, i.e. the digital filter's impulse response.
-Consequently, the filter kernel of a Gaussian filter is a Gaussian with finite support \cite[120]{dspGuide1997}.
+Consequently, the filter kernel of a Gaussian filter is a Gaussian with finite support \cite{dspGuide1997}.
 Assuming a finite-support Gaussian filter kernel of size $M$ and a input signal $x$, discrete convolution produces the smoothed output signal
