September 2023 StudentZone Quiz Solution

Product Number: ADALM2000

Question 1:

  • How will CDCinfluence the circuit if its value is changed?

Answer 1:

CDC decouples the accelerometer from noise on the power supply. A different value will filter out certain frequencies of noise.


Question 2:

  • Why should the user limit the bandwidth and what are the criteria for band limiting Xout, Yout, Zout?


Answer 2:

The bandwidth limitation is useful for noise reduction and antialiasing purposes. This can be implemented by adding capacitors at the output pins of the accelerometers. The value of the capacitor can be computed using the 3db bandwidth equation provided in the datasheet of ADXL327.
