why do we plot digital filter spectrum on 0 - 0.5 only
Respected sir/ madam I am find out why digital filter spectrum is plotted on 0-0.5 axis on x axis. Your help to understand this will be priceless. T. V. Chandra Shekar
This is the unique frequency range for discrete time systems. After this range, the spectrum starts repeating itself. This behaviour is known as the periodicity.
