Filters

In this lab, students will implement high pass and low pass filters, while learning about cut-off frequencies and stopband roll-off. Students will learn the differences between ideal and real-world filters, while implementing active and passive filters, as well as 1st and 2nd order filters. Students will identify the effect of a load on a passive filter.

This is lab 8 of 17 in the course, Measurements and Instrumentation.

LEARNING OBJECTIVES


After completing this lab, students will be able to:
  1. Use the NI Automated Measurements Board to measure the effect of filters on a signal of a given frequency.
  2. Use the NI Automated Measurements Board to measure the behavior of different filters in the frequency domain.
  3. Compare the attenuation of 1st and 2nd order filters.
  4. Identify the effect that a load has on a passive filter compared to an active filter.
 

REQUIRED SKILLS

 
  • Basic proficiency using LabVIEW
  • Basic proficiency using ELVIS III Instruments
  • Basic knowledge of components and their behaviors

NI ELVIS III

Engineering laboratory solution for project-based learning that combines instrumentation and embedded design with a web-driven experience, delivering a greater understanding of engineering fundamentals and system design.

Automated Measurements Board for NI ELVIS III

An application board for NI ELVIS III that provides students with a experimental platform for understanding and designing a signal chain for sensor integration.

LabVIEW

LabVIEW is systems engineering software for applications that require test, measurement, and control with rapid access to hardware and data insights.
