% box_filt.m: Interpolates the boxcar filter impulse response function

% GUISDAP v.8.9 16-09-27

%

% input parameters:

% width  : box lengths in us

% p_dtau : global time unit in us (global parameter)

% output parameters:

% impresp: the impulse response scaled to get unit area

%

% See also: but_filt, REC_impresp

% function impresp=box_filt(width);

function impresp=box_filt(width);

global p_dtau

wp=round(width/p_dtau);

for i=1:length(wp)

 impresp(:,i)=ones(wp,1)/wp;
