hi,

i am taking a control systems course at university and i am trying to
evaluate an impulse function [ f[t]=0 except at f[0]=1 for, say a range
of -5 top 5 ].  

i have managed to get the step and ramp functions going using the
UnitStep function, but i could not work out the Impulse function. Any
help would be appreciated.

regards,

heath
