Brilliant work sir
very nice work
Frequency is scaled by M(2) ,SO it sud be( pie/2 )and not( pie*2)??
thank u
"Scaling of frequnecy axis by a fator of M" is not true for down sampling I think.When the sentence is true, it is not downsampling , it only change some samples as zero.Downsampling will no change bandwidth if no aliasing happening.
I am afraid that's not true. Sampling-rate conversion is always going to have an effect on your discrete-time spectrum.
