Sample Assam ASSEB HS Skill Telecom Practice Questions

Try these sample questions to review concepts for the Assam ASSEB HS Skill Telecom exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1What is the primary characteristic that distinguishes a digital signal from an analog signal?
A.Digital signals consist of discrete binary states (0s and 1s), whereas analog signals are continuous waveforms.
B.Digital signals can only travel through optical fibers, while analog signals require copper cables.
C.Digital signals have unlimited bandwidth and zero attenuation over long distances.
D.Digital signals do not require any modulation for wireless radio frequency transmission.
Explanation: Digital signals represent information using discrete binary states (high/low voltage levels representing 0 and 1), whereas analog signals continuously vary in amplitude, frequency, or phase over time.
2Which standard SI unit is used to measure signal frequency in telecommunication systems?
A.Decibel (dB)
B.Hertz (Hz)
C.Ohm (Ω)
D.Watt (W)
Explanation: Signal frequency, defined as the number of complete wave cycles per second, is measured in Hertz (Hz), kilohertz (kHz), megahertz (MHz), or gigahertz (GHz).
3Which transmission mode allows data to flow simultaneously in both directions between two communicating devices?
A.Simplex mode
B.Half-duplex mode
C.Full-duplex mode
D.Unicast mode
Explanation: Full-duplex mode enables bi-directional simultaneous communication, as seen in standard telephone calls or full-duplex Ethernet connections.
4What is the function of the dielectric insulating layer positioned between the inner center conductor and outer shield in a coaxial cable?
A.It converts electrical signals directly into optical light pulses.
B.It increases signal attenuation to prevent receiver overload.
C.It acts as a ground wire to dissipate high voltage lightning surges.
D.It maintains physical spacing, provides electrical insulation, and controls characteristic impedance.
Explanation: The dielectric insulator holds the center conductor centered inside the tubular shield, prevents electrical shorting, and maintains constant characteristic impedance along the cable length.
5What happens to an electromagnetic or optical signal as it travels long distances through a transmission medium?
A.Its power level decreases due to attenuation.
B.Its frequency increases exponentially.
C.Its velocity accelerates beyond the speed of light.
D.Its phase aligns automatically into perfect synchrony.
Explanation: Attenuation is the gradual loss of signal strength (power) as a wave propagates through copper cables, optical fibers, or free space due to absorption, scattering, and resistance.
6Why are copper wire pairs twisted around each other at specific twist rates in UTP cabling?
A.To increase the overall physical breaking strength of the cable.
B.To cancel out electromagnetic interference (EMI) and crosstalk between adjacent pairs.
C.To reduce the electrical resistance of the copper conductors.
D.To allow optical light to reflect off the wire surfaces.
Explanation: Twisting two insulated conductors creates a balanced pair where external electromagnetic noise induces equal signals in both wires, canceling out crosstalk and EMI at the differential receiver.
7In Amplitude Modulation (AM), which parameter of the high-frequency carrier wave is varied in proportion to the instantaneous amplitude of the modulating signal?
A.Carrier frequency
B.Carrier phase angle
C.Carrier amplitude
D.Carrier wavelength
Explanation: In AM, the amplitude (peak height) of the high-frequency carrier wave changes in direct proportion to the amplitude of the baseband modulating signal while carrier frequency remains constant.
8If an input power of 100 mW is applied to a cable and the output power measured at the far end is 10 mW, what is the power loss in decibels (dB)?
A.-3 dB
B.-90 dB
C.-20 dB
D.-10 dB
Explanation: Power gain or loss in dB is calculated using $10 \log_{10}(P_{out}/P_{in})$. Here, $10 \log_{10}(10/100) = 10 \log_{10}(0.1) = 10 \times (-1) = -10\text{ dB}$, representing a 10 dB power loss.
9Which multiplexing technique combines multiple optical data streams onto a single fiber optic strand by transmitting each stream on a distinct wavelength of light?
A.Wavelength Division Multiplexing (WDM)
B.Time Division Multiplexing (TDM)
C.Frequency Division Multiplexing (FDM)
D.Code Division Multiplexing (CDM)
Explanation: Wavelength Division Multiplexing (WDM) combines multiple light signals of different optical wavelengths (colors) onto a single optical fiber.
10How does baseband transmission differ from broadband transmission?
A.Baseband uses optical fibers, whereas broadband uses twisted copper wire.
B.Baseband transmits unmodulated digital signals over the entire channel bandwidth, whereas broadband modulates signals onto high-frequency carriers to multiplex multiple channels.
C.Baseband allows full-duplex communication, whereas broadband only supports simplex.
D.Baseband operates exclusively over satellite links, while broadband uses terrestrial towers.
Explanation: Baseband transmission sends digital pulses directly over the medium using the entire bandwidth for a single channel (e.g., standard Ethernet), whereas broadband modulates digital data onto higher frequency radio/optical carriers allowing FDM multiplexing of multiple channels.
