Slide 3 – How does the signal know whether to go to output or controller?
Submitted by: waydo Submitted on: September 29, 2004 Identifier: L1.2 The signal actually goes to both the output and the controller. Block diagrams simply show the information flow schematically, so we can split and reroute signals arbitrarily on the diagram, even if the information is actually sent along different physical paths. [Back to Top] • Why can’t we control voltage/resistance digitally? Submitted by: waydo Submitted on: September 29, 2004 Identifier: L1.2 Sometimes we can. At a very low level, however, virtually all physical devices are controlled by analog signals. It may be, for example, that we use a motor with a digital input, but then at some lower level within the motor there is probably a digital motor controller with an output that is then run through a D/A converter to produce an analog input to the motor. The goals of a particular control task will dictate whether we need to model this level of detail or whether we can view the motor as a purely digital device. [Ba
