Thanks for a helpful forum. I have two questions.
1. I am trying to implement a simple FIR filter. All I do is sum 100 samples of
the input to get the output.
Y = X(100) + X(99)..........X(1).
I want to create a filter object for this filter. The question is - Do I use a
FORM I, or a FORM II structure, i.e, do I use dfilt.df1, or dfilt.df2 function
2. I cascade two such filters, and create a cascaded filter object. I use fvtool
to plot the magnitude response of the cascaded filter.
I have to downsample the output of cascaded filter by 100. The question I have
is how can I represent the downsampling function as a filter specification
object, so that I can cascade it to the above filter, and plot the whole
