More Information
Summary:A signal transformation apparatus capable of performing stable transformation of a signal using a Mechanical switch includes a signal generator which generates a reserve pulse signal in response to an applied sync signal, a signal controller which outputs control signals to change and transform the reserve pulse signal to pulse signals having a predetermined pulse width, and a signal modulator which transforms the reserve pulse signal to the pulse signals having different pulse widths in response to the control signals. The signal modulator includes a switch bank in which a plurality of mechanical switches are connected in parallel, and a transmission line between nodes where the mechanical switches are formed.
