Could anyone interpret the above statement for me ?
Is that means, a rectangular pulse with width of a, and is centred at point a ?
Please advice.
 

Re: rect [ (t-a)/a ] = ?

thais is very easy.rect(t/a) is located at origin having pulse width "a".ie; it extends from -a/2 to a/2. whereas rect((t-a)/a ) is shifted right by "a" units.ie,it extends from +a/2 to +3a/2.
