What purpose of modulation prevents interference when sharing the same communication path?
- Spectrum conservation
- Channel allocation
- Ease of radiation
- Companding
Correct Answer

A. Channel allocation

Explanation

Channel allocation is the purpose of modulation that prevents interference when sharing the same communication path. By allocating different channels or frequencies to different users or devices, modulation ensures that their signals do not overlap or interfere with each other. This allows multiple users to communicate simultaneously without causing interference or signal degradation. Channel allocation is a crucial aspect of efficient and reliable communication systems, especially in scenarios where multiple users or devices need to share the same communication path.

The output of the oscillator in an FM modulator increases in frequency with each
- Positive half cycle of the carrier
- Negative half cycle of the carrier
- Positive half cycle of the modulating signal
- Negative half cycle of the modulating signal
Correct Answer

A. Positive half cycle of the modulating signal

Explanation

In an FM modulator, the output of the oscillator increases in frequency with each positive half cycle of the modulating signal. This means that as the amplitude of the modulating signal increases during the positive half cycle, the frequency of the oscillator also increases. This relationship between the modulating signal and the oscillator frequency is what allows for the modulation of the carrier signal in frequency modulation.

What is the formula to find the modulating index?
- Deviation / Frequency
- Deviation x Frequency
- Sideband / Modulating Frequency
- Sideband x Modulating Frequency
Correct Answer

A. Sideband x Modulating Frequency

Explanation

The modulating index is a measure of the extent of modulation in a signal. It is calculated by multiplying the sideband and the modulating frequency. This formula is used to determine the modulation index in frequency modulation (FM) systems, where the sidebands are created by the modulation of the carrier signal with the modulating frequency. By multiplying these two values, we can obtain the modulating index, which provides information about the amount of frequency deviation in the FM signal.

At what distance should the rods be spaced in a multi-rod grounding configuration?
- 0.5 to 2 times the length of the longest rod in the subsystem
- 1.5 to 3 times the length of the longest rod in the subsystem
- 2.5 to 4 times the length of the longest rod in the subsystem
- 3.5 to 5 times the length of the longest rod in the subsystem
Correct Answer

A. 1.5 to 3 times the length of the longest rod in the subsystem

Explanation

The rods in a multi-rod grounding configuration should be spaced at a distance of 1.5 to 3 times the length of the longest rod in the subsystem. This spacing ensures that the rods are adequately spread out to provide efficient grounding and minimize the risk of electrical faults. Spacing the rods too closely together may result in inadequate grounding, while spacing them too far apart may lead to uneven distribution of electrical current. Therefore, a spacing range of 1.5 to 3 times the length of the longest rod strikes a balance between effective grounding and efficient use of resources.

Non-uniform quantizing and companding decreases the length of the code word from
- 11 to 7 bits
- 11 to 8 bits
- 16 to 7 bits
- 16 to 8 bits
Correct Answer

A. 11 to 7 bits

Explanation

Non-uniform quantizing and companding is a technique used in data compression to reduce the number of bits required to represent a signal. In this case, the original code word length is 11 bits. By applying non-uniform quantizing and companding, the length of the code word is decreased to 7 bits. This means that the signal can be represented using fewer bits, resulting in a more efficient compression scheme.

Insulation resistance increases if
- Length of insulation increases
- Area of conductor increases
- Thickness of insulating material increases
- Both thickness and length of insulating material increases
Correct Answer

A. Thickness of insulating material increases

Explanation

The insulation resistance is a measure of how well an insulating material can resist the flow of electrical current. Increasing the thickness of the insulating material can improve its ability to prevent current leakage, thereby increasing the insulation resistance. This is because a thicker insulating material provides a longer path for the current to flow through, making it more difficult for the current to pass through and reducing the chances of leakage. Therefore, increasing the thickness of the insulating material is likely to increase the insulation resistance.
