Investigation of chained analog signal processors in Programmable Analog Computer

This elaboration presents a new device based on dynamically programmable Analog Signal Processors (dpASP) developed for hard real-time control applications. The developed Programmable Analog Computer/Controller (PAC) is an open hardware for a wide range of signal processing tasks. In this report the analog signal routing and filter based signal processing realized by the dpASP is presented. This research was focused on the signals form as they are processed and transferred between analog processors. The investigation is exampled by the low-pass filter(s) embedded into every analog processor. For complex signal processing tasks a few dpASP must be routed together. The dpASP chain is created for signal diagnosis and due to the limited resources of a single device. Final conclusions related to chaining analog processors are given.
