Generate a decaying exponential function of time for using the time axis:

t $=0$:$0\mathrm{.}001$:$1$;

Set the amplitude to $255$ and the exponent to a $=-6.$ Digitize by converting to

unsigned $8$bit integer $($uint$8).$ Calculate the entropy of this signal, meaning using the formula $-$sum$($p$.*$log$2($p$))$ to this vector. Be careful because some of these probabilities may be zero, so if we just apply the formula $-$sum$($p$.*$log$2($p$)),$we might get an error. The non$-$zero elements of p must be selected and then apply the formula. The entropy is $6\mathrm{.}26$ and the entropy of the differential signal was

around $0\mathrm{.}88.$
