Area: Electronics and control
Module overview β- How do RC circuits charge, discharge and filter signals, and how do we predict their behaviour over time and frequency?The capacitor charge and discharge through a resistor, the time constant, and passive RC filters selecting signals by frequency.15 min answer β
- How do we describe, simplify and design logic circuits whose output depends only on the present inputs?Combinational logic built from logic gates, described by truth tables and Boolean expressions, simplified using Boolean algebra and Karnaugh maps.16 min answer β
- How do control systems use feedback to hold an output at a desired value, and what is the difference between open and closed loop?Control systems described by the system model, the difference between open-loop and closed-loop control, and the role of feedback, the error signal and the components of a closed-loop system.14 min answer β
- How is a microcontroller programmed to read inputs and drive outputs, and how do we plan that program?Programmable control with a microcontroller: inputs and outputs, programs described by flowcharts and pseudocode, and the use of loops, decisions and sub-routines.14 min answer β
- How do op-amp circuits amplify and combine analogue signals, and how do we predict their output?The operational amplifier as a high-gain difference amplifier, and the inverting, non-inverting, summing and difference configurations with their closed-loop gain relationships and saturation.16 min answer β
- How do logic circuits store a state and generate timing, and how do counters and timers work?Sequential logic with memory: flip-flops storing a bit, counters dividing and counting pulses, and astable and monostable timing circuits.14 min answer β
