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
