i'm confused

i confused about...

if the transmitted radio signal bandwidth > the "bandwidth" of the multipath channel, the received signal will be distorted but the received signal strength will not fade as much over a local area.

i assumed -> radio signal bandwidtgh as the input x(t) --> delta funtion
the channel as the filter h(t)---> rectangular function

When i convolved the two functions together. i found that the output y(t) is not distorted...confused..hhmmm

i used this site..to visualize...the convolution

ok thanks

hi
the rect function in time domain is not real
this function is in frequency domain
rect(f) >>>> sinc(t)
u most convulve x(t) and sinc(t)
or multiply X(f) and rect(f)
