Analysis Of Real-time System
A real time system is defined as that whose response is dependent upon a fixed frame of time. The input to the system affects the output within a defined range of time outside of which it becomes obsolete. On the converse, a normal system, which is non real time is that whose response is not depended upon a fixed range of time and hence the output is a function of both the current input and any previous inputs. For the Muddy springs bottled water company, the proposed system would incorporate operator’s ...
