Positive And Negative Clamper Circuit. Actually the positive and negative peaks of the signals can be placed at desired levels using the clamping circuits. Positive clamping occurs when negative peaks raised or clamped to ground or on the zero level in other words it pushes the signal upwards so that negative peaks fall on the zero level.
Negative clamping occurs when positive peaks raised or clamped to ground or on the zero level in other words it pushes the signal downwards so that the positive peaks fall on the zero level. As the dc level gets shifted a clamper circuit is called as a level shifter. Positive clamping occurs when negative peaks raised or clamped to ground or on the zero level in other words it pushes the signal upwards so that negative peaks fall on the zero level.
The circuit diagram to build an negative clamper is shown below.
Actually the positive and negative peaks of the signals can be placed at desired levels using the clamping circuits. Similarly a clamper circuit adds the negative dc component to the input signal to push it to the negative side. The following are two general types of clamping. The circuit diagram to build an negative clamper is shown below.
