ABSTRACT:
An n-valued switch with n≧2, with an input enabled to receive a signal in one of n states, an output enabled to provide a signal in one of at least 2 states, under control of a control signal having one of at least 2 states is disclosed. Signals are instances of a physical phenomenon, an instance representing a state. N-valued inverters are also disclosed. Different types of signals are disclosed, including optical signals with different wavelengths, electrical signals with different frequencies and signals represented by a presence of a material. A kit including an n-valued switch is also disclosed.
