Signal conversion processing apparatus

Image Number 18 for United States Patent #6147630.

A signal conversion processing apparatus for temporarily storing an input analog signal and processing the signal to generate a desired output signal includes nonvolatile semiconductor memory sections, an input control section, and a signal processing section. The nonvolatile semiconductor memory sections sequentially store the input analog signal on the basis of a predetermined first control signal in the form of an analog value. The input control section selects a nonvolatile semiconductor memory section, in which the analog signal is to be written, from the nonvolatile semiconductor memory sections on the basis of a predetermined second control signal. The signal processing section performs arithmetic processing of a plurality of analog data read out from the nonvolatile semiconductor memory sections to convert the analog data into a desired output signal in the form of an analog value.
