1.
Which of the following microphones has bidirectional feature?
2.
In TV transmitter some possible advantages of IF modulation are
- The modulator section and visual exciter can be solid state devices
- VSB filter can be introduced at low power level
- The subsequent stages following VSB filter can be tuned permanently for wideband linear operation
- It is economical
