$2\mathrm{.}30$ Represent the function

$e(t)=5sin31\mathrm{.}4t+2sin44t$

as a discrete set of $N=128$ numbers separated by a time increment of $(\frac{1}{N}).$ Use an appropriate algorithm to construct an amplitude spectrum from this data set. $($Hint: A spreadsheet program or the program Filele DataSpect will handle this task.$)$

This is in MS Excel $.$ I did all but fourier analysis goving the message that data should brne $2^2.$ By solving all the funtion g$($t$)$ is the funtion total vlue for input $.$ But fourier analysis in excel is notv accpting it $.$ Plese help.
