Are taps the same are difference equation coefficients?

I'm not sure how they can be actually – or if they are I don't know how they relate.

Yes, they are. The filter coefficients are also call taps, or tap weights.

MATLAB: Averaging daily phone taps

Hi Kristen-san,

Thank you for sharing detailed explanation. I think you can do your task more simply and more efficiently by using datetime vector and retime function. The following is an example:

% Sample time stamp data
timeStamp = datetime(2018,7,1)+21*days(rand(100,1));
timeStamp = sort(timeStamp);
% Daily count
TT = timetable(timeStamp,ones(numel(timeStamp),1));
TT = retime(TT,'daily','sum');

The result looks like:

>> TT
TT =
21×1 timetable
       timeStamp         Var1
  ___________________    ____
  2018/07/01 00:00:00      3 
  2018/07/02 00:00:00      7 
  2018/07/03 00:00:00      6 
 ...

And to obtain an average value (NOT a median value):

>> mean(TT.Var1)
ans =
  4.7619

The following will get you very close:

 Hd = fdesign.bandpass('N,Fc1,Fc2',40,500,1500,6000);
 B = design(Hd);

Compare

fvtool(B,1);
fvtool(BPF_coefficients,1)
