The impulse response and the excitation function of a linear time invariant causal system are shown in figure (a) and (b) respectively. The output of the system at t = 2 sec is equal to

Consider

Number of samples per period = 10p

This is not a rational number. Hence signal is non periodic.

? V_P = 3.46 x 10⁸ m/s.

This can be solve by using Boolean identity but using k map it will be more easy

(A + B + C) (A + B + C) (A + B + C).

Here,

a = 1.59'' = 40.386 mm = 4.04 cm

? .

Phase lag is delay between a correcting signal of control system and response to it.

Statement (ii) is false because maximum energy of photons varies linearly with frequency of incident light. It can be shown as follows :

F₁ > F₂ > F₃

j = light intensity = constant

Photocurrent V_s Anode voltage with frequency and incident light as a parameter.

The light intensity is constant.

Since number of comparators = 2ⁿ - 1 = 15;

Then number of bits are '4'

Resolution

Use the condition of controllability.

2^{n - 1} R = 32 K&Omeg;

n = 4

? 8R = 32

R = 4 K?.

V₁ = i₁R₁ + i₂R₂

i₁ + ai₁ = i₂

V₂ = i₂R₂

Putting a = - 1

= 0 V.
