MECHATRONICS EXAM 1 WITH CORRECT
ACTUAL QUESTIONS AND CORRECTLY
WELL DEFINED ANSWERS LATEST 2024 –
2025 ALREADY GRADED A+
Band pass data filtration - ANSWERS-High pass then low pass circuit connected
Cut off f=sqrt(fL*fH)
Ex: Car radio
Diode - ANSWERS-a semiconductor device with two terminals, typically allowing
the flow of current in one direction only.
Works like a valve
, Full Wave Rectifier - ANSWERS-Uses positive and negative charge of AC voltage to
produce DC voltage. (Converts AC to DC)
Transistor - ANSWERS-A small electronic device used in a circuit as an amplifier or
switch. (2 diode connected in opposite direction)
Logic gate AND OR NOT
Amplifier - ANSWERS-an electronic device for increasing the amplitude of
electrical signals, used chiefly in sound reproduction.
Combination of transistors
Zener Diode - ANSWERS-Allows current flow in one direction, but also can flow in
the reverse direction when above breakdown voltage.
Ex: voltage surge protection
Operational Amplifier - ANSWERS-An integrated circuit that is used to amplify the
difference in voltage between its two input pins by a huge gain value
2 types:
