Simplified High Frequency Broadband Tuner
By combining direct conversion to baseband with novel tuning and signal processing schemes, this invention achieves advantages such as, elimination of the intermediate signals and attendant processing; simplification of processing the near direct current signal due to the use of a novel digital signal processing (DSP) technique; a wider tuning range than is available in superheterodyne receivers; use of the novel signal processing scheme allows the use of inexpensive and readily made bandpass filters; design requirements for the phase locked loop (PLL) are simplified due to a novel tuning technique which is made possible by the novel signal processing scheme; no adjustable or high- precision tuning circuits are required.
A Fringe Field Capacitive Sensor
A fringe field, capacitive sensor for measuring the distance between a probe and the surface of the conductive body, and is especially useful for measuring the geometry of a hole.
