-
For the circuit shown in the figure, D has a transition from 0 to 1 after CLK changes from 1 to 0. Assume gate delays to be negligible
Which of the following statements is true? -
What is the major cause of creeping in an energy-meter?
-
Assertion (A): As the length of the resonant antenna is increased, the number of lobes increases and the direction of the major lobes is closer and closer to the direction of the diode.
Reason (R): As the length increases, the current distribution along the wire becomes more and more uniform.
-
In the circuit below, the diode is ideal. The voltage V is given by
