1. The real valued signal x(t), t ∈ R, has bandwidth B. Determine the bandwidth of the following signals:
2. Consider the continuous time real-valued signal
a) Find the expression of its practical bandwidth B based on the amplitude criterion. Calculate the value of B with ε = −40 dB, t0 = 30 ms and T = 1 ms.
b) Find the expression of its practical bandwidth B based on the energy criterion. Calculate the value of B with ε = 1%, t0 = 30 ms and T = 1 ms.
Discuss the dependence of the results on the signal parameters t0 and T.
