Latest Patents
Cartledge's latest patents include a "System and method for determining the envelope of a modulated signal." This invention focuses on systems and methods for determining the envelope of a modulated signal using both high bandwidth and low bandwidth samples of a hybrid signal. The hybrid signal is created by mixing the modulated signal with its carrier signal, making the systems suitable for equivalent-time or real-time oscilloscopes. Another significant patent is the "Method and apparatus for directly measuring the phase change of an optical signal." This invention describes a method for measuring the phase change of an output optical signal from a device. In this process, an input optical signal is split into two, with one passing through the device while an external stimulus is applied. The phase change of the output signal is then measured as a function of the external stimulus.
