Question

related 4 kmap and 4 feedback signals

Answer 1

This article provides insight into the Karnaugh map (K-map) Boolean algebraic simplification technique via a few examples. It also includes a brief note on the advantages and the disadvantages of K-maps.We have seen that a  (2)Feedback System is one in which the output signal is sampled and then fed back to the input to form an error signal that drives the system, and depending on the type offeedback used, the feedback signalwhich is mixed with the systems inputsignal, can be either a voltage or a current.
