Question:medium

A receiver connected to an antenna whose resistance is \(50~\Omega\) has an equivalent noise resistance of \(30~\Omega\). Calculate the receiver's noise figure?

Show Hint

Noise Figure: \[ F=1+\frac{R_n}{R_s} \] where \(R_n\) is equivalent noise resistance and \(R_s\) is source resistance.

View Solution

Match List-I with List-II:

List-I (Modulation Schemes)	List-II (Wave Expressions)
(A) Amplitude Modulation	(I) \( x(t) = A\cos(\omega_c t + k m(t)) \)
(B) Phase Modulation	(II) \( x(t) = A\cos(\omega_c t + k \int m(t)dt) \)
(C) Frequency Modulation	(III) \( x(t) = A + m(t)\cos(\omega_c t) \)
(D) DSB-SC Modulation	(IV) \( x(t) = m(t)\cos(\omega_c t) \)
