Transfer Characteristic of a diode

  1. Mar 31, 2005 #1
    Hi Guys:

    My question is this

    for the circuit in the 1st fig: sketch the transfer charcteristic "vo" versus "vI"

    the answer of this question is the 2nd fig. but i want to know that what is the logic behind this sketch or in other words how we can draw such a sketch.

    Thanks in advance

    An ideal diode has zero resistance when forward biased and infinite resistance when reverse biased. So if Vi is positive, a current Vi/R will flow, and Vo=Vi, and if Vi is negative, no current will flow, and Vo=0.
