If a continuous-time signal x(t) = cos(2πt) is sampled at 4 Hz, the value of the discrete-time sequence x(n) at n = 5 is

The Region of Convergence (ROC) of the z-transform of a causal unit step discrete-time sequence is

The term hysteresis is associated with

The differential amplifier, shown in the figure, has a differential gain of A${}_d$ = 100 and common mode gain of A${}_c$ = 0.1. If V₁= 5.01 V and V₂ = 5.00 V, than V₀ in volt (up to one decimal place) is ________.

The silicon diode, shown in the figure, has a barrier potential of 0.7 V. There will be no forward current flow through the diode. If V${}_{dc}$. In volts, is greater than
