Title: Circuit device for measuring and detecting maximum output voltage
Inventor: GERUHARUTO MAIAA
IPC: H03J7/02
Filed: 1984-02-22
Abstract: A circuit is provided for the measurement and recognition of maximum or minimum voltages coming for example from a frequency selective measurement objective and in particular from an electronic filter. A fixed measurement frequency is fed to the measurement object. The measurement object is balanced by a stepwise change of a tuning voltage. The output voltage generated by the measurement object is fed to a switch after rectification and amplification, which switch is clocked with a clock signal. The output voltages of the switch are fed to an intermediate storage. The output voltages of the intermediate storage are supplied to a differential amplifier via an intermediate switch actuated by a control clock cycle. If the output voltage reaches an extremum such as a maximum then the stepwise change of the tuning voltage is interrupted. The value determined for the tuning voltage is stored in a memory such as a random access memory, the contents of which represents the optimum for the tuning of the measurement object such as for example the filter.

Abstract: PURPOSE:To perform recognition in consideration of the information of a context by outputting the candidate of a symbol to show the information to be recognized together with confidence and selecting base on the output value of the confidence and node in the case of many candidates. CONSTITUTION:At a recognizing part 2, the pattern of the character image, voice, etc., inputted from an input part l is analyzed and the combination of the candidate symbol and the confidence is outputted by a candidate output part 7. A selecting part 8 judges the candidate symbol from the output value and the confidence in a network part 9 and selects and outputs an optimum symbol. In this case, the network part 9 is constituted of a neuron circuit network to perform association. The output value goes up and down by the teacher signal that a user for the symbol outputted by the device receives or rejects. Then, the output value of the node to show the symbol deeply related to the topic inputted up to then becomes higher. Thus, in consideration of not only the information of the pattern but also the information of the context in which the recognition object appears, the suitable candidate can be drawn.
