摘要： An a data input system includes an encoded pad having position encoding and a data input device adapted to image a portion of the encoded pad to determine position and orientation of the data input device relative to the encoded pad. The encoding pad includes a plurality of correlation windows. Each correlation window includes a primary encoding marker in form of vertical line segment and a set of secondary encoding markers in form of diagonal line segments, at least one diagonal line segment intersecting the vertical line segment at an intersection angle. Spacing of the diagonal line segments encodes the X-axis position of the input device relative to the encoding pad. Intersection angle encodes the Y-axis position of the input device relative to the encoding pad. Angle of the primary encoding marker vertical line segment within the frame of the captured image encodes the angular orientation of the input device relative to the axes of the encoded pad.

摘要： A receiver and method for identifying the frequency of an RF component in an RF signal are disclosed. The receiver includes a first mixer that receives an RF signal and mixes that RF signal with a first multi-tone LO signal that includes a plurality of tones to generate a mixed signal. The output of the first mixer is filtered by a first filter that removes signals outside of a predetermined band to generate a first IF signal. A processor determines the RF frequency of the component utilizing the first IF signal and a second IF signal generated using a second multi-tone LO signal having a different plurality of tones from said first multi-tone signal. The first and second multi-tone LO signals can be generated by clocking suitable digital sequences into the mixer either by using different sequences or by using the same sequence clocked at a different rate.

摘要： An upconverting circuit is disclosed. The upconverting circuit includes a polyphase component generator that provides Np polyphase components at each input polyphase cycle, wherein Np>2 on each input polyphase cycle defined by a clock. A memory stores the polyphase components from at least one polyphase cycle prior to the current polyphase cycle. A plurality of filters process the polyphase components stored in the memory. Each filter processes a plurality of the polyphase components to generate a filtered polyphase component corresponding to that filter. A multiplexer outputs the filtered polyphase components in a predetermined order to generate a filtered output signal. In one embodiment, each filter utilizes the same functional relationship to generate the filtered polyphase components. In another embodiment, the memory is a shift register. The filters can be of arbitrary complexity.

摘要： A test measurement system and method which uses parallel digital samples of an input measurement signal to determine a trigger point for a predetermined trigger waveform. The system correlates the predetermined trigger waveform with digital samples of the input measurement signal. The result of this correlation is then used to identify a trigger point. Generally the point in time where the trigger waveform has the strongest correlation with the digital samples identifies the desired trigger point. This trigger point is then used to identify the selected measurement data, where the selected measurement data corresponds to the digital samples obtained at the trigger point time.
