Choices:
A. FSK
B. Two-tone modulation
C. PCM
D. Single-tone modulation
✅ Answer: A. FSK
📝 Explanation: Frequency Shift Keying (FSK) is widely used in telegraphy due to its noise resistance and efficiency.
Q62. The commercial frequency deviation of FM is ______.
ایف ایم کے لیے تجارتی فریکوئنسی انحراف ______ ہے۔
Choices:
A. 70 kHz
B. 75 kHz
C. 80 kHz
D. 65 kHz
✅ Answer: B. 75 kHz
📝 Explanation: In commercial FM broadcasting, a maximum deviation of 75 kHz is standard for clear signal transmission.
Q63. The color of an object is decided by ______.
کسی چیز کا رنگ ______ کے ذریعے متعین ہوتا ہے۔
Choices:
A. The reflected color
B. The wavelength transmitted through it
C. Reflected color for opaque objects and wavelength transmitted through it for transparent objects
D. None of the above
✅ Answer: C. Reflected color for opaque objects and wavelength transmitted through it for transparent objects
📝 Explanation: Opaque objects reflect light to show color, whereas transparent objects allow specific wavelengths to pass through.
Q64. In a Pulse Code Modulation (PCM) system, ______.
پلس کوڈ ماڈیولیشن (PCM) سسٹم میں ______۔
Choices:
A. Large bandwidth is required
B. Quantizing noise can be overcome by companding
C. Quantizing noise can be reduced by decreasing the number of standard levels
D. Suffers from the disadvantage of incompatibility with TDM
✅ Answer: B. Quantizing noise can be overcome by companding
📝 Explanation: Companding (compressing and expanding) reduces quantization noise, improving PCM signal quality.
Q65. Which of the following statements is correct?
درج ذیل میں سے کون سا بیان درست ہے؟
Choices:
A. Convex lens has positive focal power, and concave lens has negative focal power
B. Convex lens has negative focal power, and concave lens has positive focal power
C. All lenses have positive focal power
D. All lenses have negative focal power
✅ Answer: A. Convex lens has positive focal power, and concave lens has negative focal power
📝 Explanation: Convex lenses converge light and have positive focal power, while concave lenses diverge light and have negative focal power.
Adver
Q66. In modulation, a "carrier" is ______.
ماڈیولیشن میں "کیریئر" ______ ہوتا ہے۔
Choices:
A. Resultant wave
B. Speech voltage to be transmitted
C. Voltage with constant frequency, phase, or amplitude
D. Voltage for which frequency, phase, or amplitude is varied
✅ Answer: C. Voltage with constant frequency, phase, or amplitude
📝 Explanation: A carrier is a stable wave that carries information by varying its frequency, phase, or amplitude.
Q67. To eliminate ghosts in a TV picture, ______ should be done.
ٹی وی تصویر میں گھوسٹ امیج کو ختم کرنے کے لیے ______ کرنا چاہیے۔
Choices:
A. Use a longer transmission line
B. Connect a booster
C. Change the antenna orientation or location
D. Twist the transmission line
✅ Answer: C. Change the antenna orientation or location
📝 Explanation: Ghosting occurs due to signal reflection, which can be minimized by adjusting the antenna's position.
Q68. The frequency range of 300 kHz to 3000 kHz is known as ______.
300 kHz سے 3000 kHz کی فریکوئنسی رینج ______ کے طور پر جانی جاتی ہے۔
Choices:
A. Low frequency
B. Medium frequency
C. High frequency
D. Very high frequency
✅ Answer: B. Medium frequency
📝 Explanation: Medium frequency (MF) ranges from 300 kHz to 3000 kHz and is commonly used for AM radio broadcasting.
Q69. Which of the following does not cause losses in optical fiber cables?
درج ذیل میں سے کون سا آپٹیکل فائبر کیبلز میں نقصان کا سبب نہیں بنتا؟
Choices:
A. Stepped index operation
B. Impurities
C. Microbending
D. Attenuation in glass
✅ Answer: A. Stepped index operation
📝 Explanation: Stepped index fibers reduce loss by maintaining light reflection within the core.
Q70. For a low-level AM system, the amplifier’s modulated stage must be ______.
کم سطح کے AM سسٹم کے لیے، ماڈیولیٹڈ اسٹیج کا ایمپلیفائر ______ ہونا چاہیے۔
Choices:
A. Linear devices
B. Harmonic devices
C. Class C amplifiers
D. Non-linear devices
✅ Answer: A. Linear devices
📝 Explanation: Low-level AM requires linear amplification to maintain signal integrity and avoid distortion.
