✅ Answer: C. 20 kW
📝 Explanation: Standard A earth stations typically have a power output of around 20 kW for satellite communication.
Q94. PAM stands for:
PAM کا مطلب کیا ہے؟
Choices:
A. Pulse Analogue Modulation
B. Phase Analogue Modulation
C. Pulse Amplitude Modulation
D. Phase Amplitude Modulation
✅ Answer: C. Pulse Amplitude Modulation
📝 Explanation: In PAM, the amplitude of pulses varies according to the modulating signal.
Q95. The characteristic impedance of a twin-wire feeder used for TV signals is about:
ٹی وی سگنلز کے لیے استعمال ہونے والے ٹوئن وائر فیڈر کی خصوصیتی امپیڈینس کتنی ہوتی ہے؟
Choices:
A. 1000 ohm
B. 500 ohm
C. 300 ohm
D. 100 ohm

Adver
Q96. In an FM receiver, the amplitude limiter:
ایف ایم ریسیور میں ایمپلیٹیوڈ لیمیٹر کا کیا کام ہے؟
Choices:
A. Amplifies low-frequency signals
B. Reduces the amplitude of signals
C. Eliminates any change in amplitude of received FM signals
D. None of the above
✅ Answer: C. Eliminates any change in amplitude of received FM signals
📝 Explanation: The amplitude limiter ensures that FM signals remain unaffected by amplitude variations due to noise.
Q97. A buffer amplifier is:
بفر ایمپلی فائر کیا ہوتا ہے؟
Choices:
A. A double-tuned amplifier
B. A high-gain D.C. amplifier
C. A cathode follower stage
D. None of the above
✅ Answer: C. A cathode follower stage
📝 Explanation: A buffer amplifier provides impedance matching and isolates stages of a circuit.
Q98. Leak-type bias is used in plate-modulated class C amplifiers to:
پلیٹ ماڈیولیٹڈ کلاس C ایمپلی فائر میں لیک-ٹائپ بائیس کا استعمال کیوں کیا جاتا ہے؟
Choices:
A. Increase the bandwidth
B. Prevent overmodulation
C. Prevent excessive grid current
D. Prevent tuned circuit damping
✅ Answer: C. Prevent excessive grid current
📝 Explanation: Leak-type bias prevents excessive grid current and distortion in class C amplifiers.
Q100. One of the advantages of base modulation over collector modulation in a transistor class C amplifier is:
