Abstract
A waveshaping circuit for providing logic levels from a voltage source to a digital circuit comprising a pull-up (or pull-down) resistor for converting the voltage source into voltage signals of predetermined values, a low-pass filter connected to the resistor for eliminating noise components of the voltage signals, a voltage limiter for limiting the voltage signals to a predetermined voltage range, and a voltage divider for receiving and dividing the voltage signals to supply output voltages of high or low logic levels to the digital circuit.
