hi guy,

i am doing so self learning in signal processing...i kinda confuse some symbol in the reading..urgently need some expertise to kill the confusion...can anyone read my attachment what and how the symbol stand for...

THanks

ANthony

 

symbol one looks like tau

your going from zero to t ... in the second

 

Additionally, the S-like symbol is used to show integration is carried out.

 

in order to express 'the integral from t to 0', just reverse the positions of the 0 and t

 

what does "tau" could be meaning in that situation when ( t - tau ) ?

 

it is a change in time from t, similar to delta t

 

thanks guy...
