• Eg. Gain, Output noise level, Bandwidth, Input
  voltage level, etc
• Eg. Frequency, Bandwidth, Resonance frequency,
  etc
• Height, Weight, Material type, etc

4
References

• Technical journals

• Technotes
• Technical Handbooks

5
Equipment Logistics

• Oscilloscope, PCB board, Simulation software,
  Chemical etchant or Mechanical etching system,etc
• Accelerometer, or Piezoresistive device, ADC,
  DSP, Labview for DAQ, etc
• Cranes, Bolts and nutts, Beams, Concrete, etc,
  Structure simulators, etc

6
Project Schedule

• Produce Gantt Chart

7
Cost

• Equipment and logistic cost
• Man-hour cost, from Gantt chart

8
Modelling

• Use of drawing board, manual calculations
• Use CAD design tool

9
Simulation

• Use of application software to simulate model
• Eg, Labview, Matlab simulink, PSpice, HSpice,
  Synopsis, CFD, etc

10
Fabrication

• Fabricate subject following final model

11
Test And Measurement

• Check whether experimantal results fits modelled
  results,
• If fitting is good, accept model and thus
  product, otherwise, modify model by fine tuning
  it to fit the experimental result. After knowing
  the reason for the deviation, compensate it in
  the experiment.

12
Packaging

• Package subject.
