bias modulation meaning in Hindi

Examples

1. This choice prevents the feedback control from compensating for the modulation by changing the tip-sample spacing and minimizes the displacement current 90?out-of-phase with the applied bias modulation.
2. A small, high frequency sinusoidal modulation voltage is superimposed on the A . C . component of the tunneling current is recorded using a lock-in amplifier, and the component in-phase with the tip-sample bias modulation gives dI / dV directly.
