Abstract
A signal processing device having at least one input for analog input signals and one shift register or a corresponding data memory, an analog/digital converter and a processor for processing the digital signal train forming the output signal of the analog/digital converter, the signal train representing the signal course - which is preferably to be displayed in a display field - wherein the shift register is embodied as a digitally operating high-speed shift register or RAM and is connected to the output side of the analog/digital converter, in particular directly or with a data buffer interposed between them.
Claims18
A signal processing device, comprising:
- at least one input for receiving analog input signals,
- a shift register,
- an analog/digital converter receiving said analog signal and producing an output signal which is a digital signal train, and
- a processor comprising a memory for processing said digital signal train forming said output signal of said analog/digital converter, said digital signal train representing said analog signal that is to be displayed in a display field, said shift register being a digitally operating high-speed shift register and being connected to receive said output signal from said analog/digital converter,
- an input control means for controlling said analog/digital converter and said high-speed shift register, said input control means producing a data selection pulse and including a timer,
- means for storing said digital signal from said shift register in said memory, said means for storing being controlled by a data selection pulse from said input control means,
- said input control means being a separately programmable and separately timed control module.
