Finite State Machine A finite state machine (FSM) is either deterministic or non-deterministic. A deterministic FSM (DFSM) is a FSM with at most one transition for each symbol and state. A non-deterministic FSM (NDFSM) is a FSM whose transition function maps input symbols and states to a (possibly empty) set of next states. T

Plot the frequency response and the poles and zeroes in each case. Use a sampling frequency of one rad/sec. Compare the filter frequency responses. (See attachment for full question).

A two-port bridge connects on the end of a cable of length X m. to the end of a similar cable of length 3x/2 m. Hosts are attached at various points on the cable system, which operates as a shared-access LAN implementing the CSMA/CD protocol with a minimum frame length of 512 bits. The bridge imparts a delay in forwarding frame
