I am having problem to understand Fourier transform in practical way
I have done some work to understand Fourier transform
in communication signal can be represent in term of time and frequency
Time domain- curve of amplitude over time axis
example
I have 5volt amplitude signal that start with t=-1 and end with t=1
function f(x)= x limit -t to +t
f(x)=5 -1 to +1
frequency domain- curve of amplitude over frequency axis
I have 5volt amplitude signal that start with f=-3 hz and end with =3hz
function f(x)= x limit -fz to + fz
f(x)=5 -3 to +3
transform - convert one domain to another domain with no loss of information
frequency domain<> timedomain
can anyone tell me how to use fourier transform in practical way
