5- An aualog-to-discrete converter is desigued
25 pts as x[n]=x_(a)(nT).
In an attempt to recover the analog sigual from
its samples x[n], a (D)/(A) converter is desigued
where x_(1)(t) is a sigual defined as:
x_(1)(t)=x[n]e^(-a(t-nT)) if nT<=t<(n+1)T
Design the LTI filter which would get
{:x_(r)(t)=x_(a)|t) if the Nyguist rate is
6- Find the Fourier trangforms of the
