| Q. |
In microwave oscillators, negative resistance transistors and diodes are used in order to generate oscillations in the circuit. |
| A. | true |
| B. | false |
| Answer» A. true | |
| Explanation: in microwave oscillator, for a current to flow in the circuit the negative impedance of the device must be matched with positive impedance. this results in current being non-zero and generates oscillation. | |
