Study Notes
Smart Systems ME 4SS3
- Course offered by Dr. S. Andrew Gadsden, Department of Mechanical Engineering, McMaster University
- Course content includes: Introduction to Signal Conditioning, Operational Amplifier, Filtering, Pulse Width Modulation, Electromagnetic Interference
L14.1 Introduction to Signal Conditioning
- Measurement system output signals often require processing to be suitable for the next stage
- Examples include amplifying weak signals, removing noise, converting non-linear to linear signals or converting analog to digital signals
L14.2 Operational Amplifier
- An amplifier is a system with inputs and an output
- Voltage gain of an amplifier = ratio between output and input voltage relative to ground
- Input impedance of an amplifier = input voltage / input current
- Output impedance = output voltage / output current
L14.3 Filtering
- Filtering is used to remove a certain frequency band from a signal while allowing others through
- Filter characteristics are described by pass band (frequencies transmitted), stop band (frequencies not transmitted), and cutoff frequency (boundary)
- Filters can be classified according to the frequency ranges they transmit or reject, including low-pass, high-pass, band-pass and band-stop
- Passive filters use only resistors, capacitors and inductors
- Active filters include an operational amplifier
L14.4 Pulse Width Modulation (PWM)
- PWM is used in control systems to control the average value of a DC voltage
- If a constant analog voltage is chopped into pulses, the average voltage value can be changed by varying pulse width
- Duty cycle is the fraction of the cycle for which the voltage is high
L14.5 Electromagnetic Interference (EMI)
- EMI is an undesirable effect on circuits caused by time-varying electric and magnetic fields
- Common sources include fluorescent lamps, DC motors, relay coils, household appliances, and car electrical systems
- EMI can be reduced using shielding, twisted pair cables or placing components farther apart
