4. What is a clipper?
• The process of limiting a wave to some arbitrary levels is called Clipping.
• The circuit that limit the amplitude of an output is called a clipping circuit.
• This is known as CLIPPER.

5. General Categories of Clippers
• There areTwo majorCategories of Clippers.
• 1 Parallel
• 2 Series

6. Unbiased parallel Clipper
Unbiased parallel clipper acts as a half
wave rectifier.
In this case input is a sine wave and diode is
considered to be an ideal diode.

8. Unbiased Parallel Positive Clipper
• In positive unbiased Clipper , Positive portion of sine wave clipped out and
we got only negative portion of sine wave.

12. Unbiased Parallel Negative Clipper
• In positive unbiased Clipper , negative portion of sine wave clipped out and
we got only positive portion of sine wave.

16. Unbiased Series Clipper
Unbiased series clipper acts as a half wave
rectifier.
In this case input is a sine wave and diode is
considered to be an ideal diode.

• In positive unbiased Clipper , Positive portion of sine wave clipped out and
we got only negative portion of sine wave.

• In negative series unbiased Clipper , negative portion of sine wave clipped
out and
we got only positive portion of sine wave.
