Analog Communications Internship Test

Intern has to take Analog Communications internship test in which they will be asked 50 multiple-choice questions. They have to score grade A or A* on this test to be eligible for the internship. Here’s a sample set of questions on the Analog Communications topic.

1. Which device is used for tuning the receiver according to incoming signal (especially in TV)?
(A) Low pass filter
(B) High pass filter
(C) Zener diode
(D) Varacter diode
View Answer

Answer: D
Explanation: Varactor diode is a diode working in the reverse-bias because of which no current flows through it. It has variable capacitance which varies with applied voltage. Varactor diodes are mainly used in Voltage Controlled Oscillators (VCOs) and RF Filters for tuning the receiver to the incoming signal or different stations.

2. A heterodyne frequency changer is ________
(A) Mixer
(B) Demodulator
(C) Modulator
(D) Local Oscillator
View Answer

Answer: A
Explanation: A mixer is a nonlinear electrical circuit that multiplies two signal frequencies applied to it, and produces a new frequency. Mixers are widely used to shift signals from one frequency range to other, which is known as heterodyning process. Generally, Local Oscillator generates a frequency to be applied at one of the input terminals of the mixer. Demodulator decodes the message signal from modulated signal, while modulator encodes message signal for transmission.

3. What is Carrier swing?
(A) Frequency deviation
(B) Width of sideband
(C) Instantaneous frequency
(D) Total variation in frequency
View Answer

Answer: D
Explanation: Carrier swing is defined as the total variation in frequency from the lowest to the highest point. It is equal to twice the frequency deviation of FM signal. The rest of the options are parameters in FM.

4. Low frequency noise is ________
(A) Flicker noise
(B) Shot noise
(C) Thermal noise
(D) Partition Noise
View Answer

Answer: A
Explanation: Flicker noise is a type of electronic noise which is generated due to fluctuations in the density of carrier. It’s also known as 1/f as it’s power spectral density increases with a decrease in frequency or increase in offset from a signal.

5. Square Law modulators ________
(A) used for amplitude modulation
(B) have non linear current-voltage characteristics
(C) have non linear current-voltage characteristics as well as used for Amplitude Modulation
(D) used for frequency modulation
View Answer

Answer: C
Explanation: Square law modulators are used for amplitude modulation and have non-linear current-voltage characteristics. The output of Square law demodulator is said to vary with respect to square of the input. They are highly linear in low voltage region.
