Define Causal System - Discrete Time Systems?
A causal system is one which produces an output only when there is an input. All physical systems are causal. In general, a causal discrete-time sequence, x[n], or the impulse response, h[k], of a discrete-time system is zero before time 0, that is x[n] = 0, n < 0, or h[k] = 0, k < 0. The input-output relationship of a Linear Time Invariant (LTI) system is given by the convolution sum
Where h[k] is the impulse response of the system. The values of h[k] completely define the discrete-time signal in the time domain.
Q. Consider a reverse-biased diode with a source voltage VB in series with a load resistance RL. Write the KVL equation for the circuit.
Describe the physical properties and uses of the Brasses. Brass - It is an alloy of copper and zinc along with 60 percent copper and 40 percent zinc. Its properties are- 1.

Q. For a parallel-plate capacitor with plates of area A m 2 and separation d m in air, the capacitance in farads may be computed from the approximate relation Compute the
Measures for Improving Joints and Connection 1. Spacing of poles: The spacing between poles (for overhead lines) is also an important requirement. Long spans will result in
Energy Bands 1) Since isolated atoms are brought together to make a solid, the electron wave functions begin to overlap. 2) Several interactions occur, and, at the proper i
Figure 1(a) shows a simple one-stage MOSFET amplifier. The input-output relationship is graphed in Figure 1(b), where the solid curve indicates operation in the saturated region an
