Question
9-1) Lathi & Ding, Prob. P.5.1-10
(a) A first-order-hold circuit can also be used to reconstruct a signal g(t) from its samples. The
impulse response of this circuit is
h(t) = A
(
2Ts
12
where Ts is the sampling interval. Consider a typical sampled signal ğ(t) and show that this
circuit performs the linear interpolation. In other words, the filter output consists of sample
tops connected by straight-line segments. Follow the procedure discussed in Sec. 5.1.2
(Fig. 5.6) for a typical signal g(t).
(b) Determine the transfer function of this filter and its amplitude response, and compare it with
the ideal filter required for signal reconstruction.
