I want to design a simple moving avergae filter object with window size 5 and cutoff frequency 0.3 (scaled to 1).
using dsp.MovingAverage() doesn't return a filter object.
(I need a filter object to visualize the filter using fvtool)
Please help me with this,
Thanks.

Hi Varun, to learn more about usage of moving average filter you can follow the following links:
Moving average - MATLAB (mathworks.com)
How Is a Moving Average Filter Different from an FIR Filter? - MATLAB & Simulink (mathworks.com)
for the purpose of your reference here is a sample example:
movAvg = dsp.MovingAverage(10,'Method','Sliding window');
input = randn(1024,1);
filterOutput = movAvg(input);
fvtool(filterOutput,1)
