Q1. Biot Savart law states that

The magnetic flux density at a point due to a current element is normal to the plane containing the element and the line joining the element and the point.

The magnetic flux density at a point due to a current element is in phase with the plane containing the element and the line joining the element and the point.

The magnetic flux density at a point due to a current element is at 45° to the plane containing the element and the line joining the element and the point.

The magnetic flux density at a point due to a current element is in phase opposition to the plane containing the element and the line joining the element and the point.

Q2. A Signal has frequency components from 300 Hz to 1.8 KHz. The minimum possible rate at which the signal has to be sampled is more than ______.

2.1 KHz

3.6 KHz

600 Hz

1 KHz

Q3. What is the Z-Transform of the unit step sequence \(u[n]?\)

\(\frac{1}{(1 - z^{-1})}\)

\(\frac{1 - z^{-1}}{z - 1}\)

\(\frac{z}{z-1}\)

\(\frac{z-1}{z}\)

Q4. What is the frequency-domain representation of a discrete-time signal \(x[n]\)?

\(X(\omega) = \int_{-\infty}^{\infty} x(t) e^{-j\omega t} dt\)

\(X(\omega) = \sum_{n=-\infty}^{\infty} x[n] e^{-j\omega n}\)

\(X(\omega) = \int_{0}^{\infty} x(t) e^{-st} dt\)

\(X(\omega) = \int_{-\pi}^{\pi} X(e^{j\omega}) e^{-j\omega t} d\omega\)
