PASSIVE TOOLS 1 is a versatile collection of passive utilities in 4 HP. It consists of 4 signal processors. MASH is an esotheric diode/transistor-based signal interwinder, OR is a diode maximum selector/passive logic OR, M0RE is a straightforward positive half-wave rectifier and HPF is an RC high pass filter with three selectable cutoff frequencies. The module draws no power and combines four useful functions in a tiny package.
