Implementation of Signal Advance Technology
The functional block diagram shown in the image at right, depicts a typical closed-loop control (interventional) system. A sensor detects a physical parameter and converts it to an analog electrical signal which reflects the value of the parameter. The signal is then processed and an output (feedback) response is generated. Each of these steps requires a finite amount of time to complete. If signal detection takes 2 ms, signal processing for 6 ms and response generation is 2 ms, the overall response time totals 10 ms.
