An signal conditioning apparatus and method to condition a human voice signal for input to a time-domain voice recognition system. The signal conditioner normalizes sampled human voice inputs so that all inputs result in an output with substantially the same pitch and frequency bandwidth characteristics. The signal conditioner includes a pitch altering circuit that alters the pitch of the input human voice signal and a frequency band limiting circuit that limits the range of spectral information contained in a signal. The pitch altering circuit converts the input into a digital signal at a first conversion rate and converts the digital signal back to an analog signal at a second rate which is unequal to the first rate. The frequency band limit circuit is a plurality of filters at different points in the frequency spectrum.

Signal conditioning apparatus

An apparatus and method for visualizing a scene in the form of image rays projecting along a path includes a plurality of charge coupled device detectors disposed along the path to receive the image rays and to collect data. This data includes both noise data which is collected at a generally constant rate, and image data which is collected when the image rays are present along the path. A clock which facilitates discharge of the data from the image array has a first state wherein the data is retained in the detectors, and a second state wherein the data is discharged from the detectors. An event detector including a plurality of charge coupled device detectors forms an event array which places the clock in the first state when the image rays are present along the path and places the clock in the second state when the image rays are absent from the path. Accordingly, the noise data which combines with the image data in the image detectors is limited to that which accumulates while the image rays are present along the path.
