Shown below is a PCM signal in which the binary symbols 1

Shown below is a PCM signal in which the binary symbols 1 and 0 are repre- sented as amplitudes of +1 volt and -1 volt respectively. The code word used consists of two bits. +1 -1 - Tb i.) Determine the sampled version gs(t) of the analog signal g(t) from which this PCM signal is derived. ii.) Assuming that g(t) is strictly band-limited with a bandwidth of W Hz, and that there is no aliasing, then g(t) can be reconstructed from gs(t) by using an ideal LPF. What is the frequency response H(f) of this LPF? What is the impulse response h(t) of this filter? iii.) Using the convolution integral obtain an expression for g(t) in terms of 96(t) and h(t).
