NETW320 – Converged Networks with Lab Lab #7 Title: CODEC Selection for a WAN Introduction A codec is a device capable of performing encoding and decoding on a digital signal. Each codec provides a different level of speech quality. The reason for this is that codecs use different types of compression techniques in order to require less bandwidth. The more the compression‚ the less bandwidth you will require. However‚ this will ultimately be at the cost of sound quality‚ as high-compression/low-bandwidth

Consider a linear time-invariant (LTI) system with impulse response h(t) whose Fourier transform is H(f ) = ∧(f ). Recall that ∧(f ) is non-zero only from f = −1 to f = +1. Find the output of the system if the input is: (a) x(t) = sin 0.5πt Solution: ∧(0.25) sin 0.5πt = 0.75 sin 0.5πt (b) x(t) = cos 10πt Solution: ∧(5) cos 10πt = 0 Question 2: [6 points] An input signal x(t) = sinc (4t) is applied to to an LTI system with impulse response h(t) = sinc (6t). Let the output of the LTI system is y(t)

circuit‚ a pole–zero pair is introduced into the open loop transfer function. Lead compensator is a component in a control system that improves an undesirable frequency response in a feedback and control system. Besides that‚ it also provides phase lead in its frequency response. Lead compensator also helps to improve transient response and a small change in steady-state accuracy.Therefore‚ modification of the circuit are to be taken place to meet the desired performance specification.
