A

Negative feedback in transistor amplifier has the advantage of :
(A) Extended bandwidth (B) Improved loop gain
(C) Increased harmonic distortion (D) All the above 3

The feedback in an amplifier circuit reduces the gain ta 50%. The feedback factor is :

(0) -1.5 18 (8) -0.5 ‏قله‎
‎(© -3 ष (0) 1.5 ५४

For an LC tuned circuit, :

(A) When the capacitor energy is maximum, the inductor energy is minimum
(B) When the capacitor current is maximum, the inductor current is minimum
(C) When the capacitor voltage is maximum, the inductor voltage is minimum
(D) When the capacitor voltage is maximum, the inductor energy is minimum

Fastest of all logic families :

(A) Emitter coupled logic (B) Resistor Transistor logic

(C) CMOS logic ൩) Transistor - Transistor logic
AD 670 is a:

(A) Successive approximation ADC (B) Dual slope ADC

(C) Counter ramp ADC (D) Flash ADC

Noise due to random emission of electrons associated with charge flowing across a potential

barrier is known as:
(A) Thermal Noise ‏برق‎ White Noise
(C) Cosmic Noise (D) Shot Noise

A broadcast radio transmitter radiates 5 kW power when the modulation percentage is 60%.

‘The carrier power is :
(A) 1.19 kW (B) 3.12kW
© 423 KW (0) 6.46kW

The advantage of DSB over SSB full carrier AM is :
(A) Less available channel space
(B) More stable transmitter gives better reception
(C) More power to transmit same signal

(D) Signal is less resistant to noise
