1. Problem Statment:
Sketch the sequence x(n)=[itex]\delta[/itex](n) + exp(j[itex]\theta[/itex])[itex]\delta[/itex](n-1) + exp(j2[itex]\theta[/itex])[itex]\delta[/itex](n-2) + ...
3. Attempt at the Solution:
The angle theta is given in this case Can someone remind me of how to multiply a complex exponential by a delta function? This sequence represents impulse signals. Such multiplication yields a real and imaginary component. Would I ignore the imaginary component and essentially keep the cos(k[itex]\theta[/itex])? Thanks very much.
