- To eliminate ghosts in the picture
- Circular polarization
- If in a broadcasting studio, a 1000 kHz carrier is modulated by an audio signal of frequency range 100-5000 kHz, the width of channel is __________ kHz.
- In Modulation, “carrier” is
- For a plate-modulated class C amplifier the plate supply voltage is E. The maximum plate cathode voltage could be almost high as
- A cordless telephone using separate frequencies for transmission in base and portable units is known as
- In TV systems, equalising pulses are sent during
- For a given carrier wave, maximum undistorted power is transmitted when value of modulation is
- The modulation index of an FM is changed from 0 to 1. How does the transmitted power change?
- The maximum power output of a standard A earth station over the total band allocated to satellite communication is about
