Abstract: The invention provides a method for removing noise spikes from an electrical input signal having an AC component, comprising the steps of determining the actual rms value of the input signal, low pass filtering the input signal, producing a variable offset, said variable offset being a function of the actual rms value, forming a variable threshold by superimposing the variable offset to the low pass filtered signal, comparing the input signal to the variable threshold, creating a spike detection signal when the input signal passes the variable threshold, and blanking the input signal during the occurrence of the spike detection signal.

Abstract: An electric low-pass filter with blocking behavior for a predetermined rejection frequency, comprising a series connection including a FIR filter and an IIR filter, with the parameters of the FIR filter being matched in essence with respect to the blocking behavior at the rejection frequency and the parameters of the IIR filter being matched in essence with respect to the low-pass behavior. It is possible with such a filter to obtain good low-pass behavior with very high attenuation of the frequency to be rejected, with relatively low circuit expenditure and high stability with respect to oscillation tendency.

Abstract: An LCD display driver providing adjustable contrast independently of multiplexing requirements by generating each COM signal in a time slot of a repeating signal frame, each COM signal containing one or more active periods and one or more inactive periods, the relative time proportions of which are adjustable, and corresponding SEGMENT signals turn on/off required segments while maintaining an essentially zero DC component, the logic levels and the relative active time and inactive times of the COM and segment signals being adjustable for increasing or decreasing the RMS voltage levels across the LCD element as desired.
