ECE 1004 TEST 3 WITH COMPLETE SOLUTIONS 100%
VERIFIED
Combinational Logic - ANSWER no memory involved, output depends only on input
Sequential Logic - ANSWER Digital circuitry in which the output state of the circuit
depends not only on the states of the inputs, but also on the sequence in which they
reached their present states.
Finite State Machine (FSM) - ANSWER A model of some types of computation that
consists of a set of input rules and output conditions and a set of transitions between
states. Generates an output as processing takes place.
clock signal - ANSWER Oscillates between a high and a low state and is utilized like a
metronome to coordinate actions of circuits.
flip-flops - ANSWER building block for sequential circuit
has two stable states
stores 1 bit of information
The output of one inverter is tied to the input of the other
Simple flip-flop - ANSWER No way to control the state
Q is high notQ is low
notQ is high Q is low
Active element - ANSWER needs power to work
, op-amp - ANSWER two voltage sources ground reference between them
Output Voltage - ANSWER proportional to difference between input pins (noninverting
and inverting inputs)
v0 = Avd = A(v2-v1)
A is open loop gain (multiplier)
Infinite for Op-Amps - ANSWER open-loop gain (no feedback)
resistance of two inputs
therefore it will not affect node it is attached to
Feedback in op-amps - ANSWER output of op-amp fed back into output
negative feedback - ANSWER feedback to the inverting terminal
allows system to be stable despite fluctuations
positive feedback - ANSWER leads to oscillations
Comparator - ANSWER Op-amp with no feedback
Ff = infinity (not connected)
Op-amp - ANSWER has feedback
RF = some finite value
