1.	Finite state machines have(a) Past memories also(b) Only present and future memories(c) Only future memories(d) Only present memoriesI have been asked this question during an interview for a job.My enquiry is from Convolution Encoding and Decoding topic in division Channel Coding of Digital Communications
Answer» Correct option is (a) Past MEMORIES also Easy explanation: A convolution encoder belongs to a CLASS of device called as FINITE state MACHINES which are those machines that have a memory of past signals.
