3. Large Shunt Capacitance
4. Short Transit Time
5. Increase Noise Figure
7) The Biggest Disadvantage the IMP ATT Diode has is its
1. Low Efficiency
2. High Noise
3. Low BW
4. Inutility to provide Pulse Operation
5. Low Power handling Ability
8) In AM transmission the Frequency, Which is not transmitted is

4. HF
10) The Modulation System inherently is most Noise Resistant in
1. SSB Suppressed carrier
2. FM
3. PPM
4. PCM
