A method of reducing by-product deposition inside wafer processing equipment includes providing a chamber having a peripheral inner wall and placing a semiconductor wafer within the chamber. The system uses a unique approach to browser development in order to allow for the delayed transformation of data which has undergone either a change to its actual value, or a change in its relationship to other data. The modulator further includes a second adder configured to receive a second integrated path from the second integrator, a first integrating path from the first integrator and a first summing path from the input signal.
