Class B Output

Class B Output. Biasing the Class B Output. * No DC current is used to bias this configuration. *Activated when the input voltage is greater than the Vbe for the transistors. * npn Transistor operates when positive, pnp when negative. * At a zero input voltage, we get no output voltage.
