A Second-Order Mechanical System
Introduction
Second order systems appear often when modeling mechanical systems see for example the handout
on the semicircular canal in the human vestibular system. In this lab you will estimate the physica

Notes for Doppler lab writeup:
1. This lab does not require a formal writeup.
2.
3. Be sure to answer the questions in the lab handout:
a. What changes did you notice in the Doppler signal as you changed the
motor voltage?
b. What does the Doppler equatio

Numerical Calculation of Fourier Series Coefficients with the FFT
As described in Lathi section 6.6, pages 658-660, the Matlab FFT function can be used to
calculate the Fourier Series coefficients of a sampled periodic signal, like the ECG you recorded
in

Introduction:
Continuous Wave (CW) Doppler ultrasound is an inexpensive, non-invasive technique
for monitoring blood flow in vivo. A typical CW Doppler is pictured below.

A Temperature Sensor as a First Order Device
Introduction
Biomedical instruments often contain a front end, composed of a transducer, an amplifier, and
some type of filter(s). Together they generate the signal(s) analyzed and/or displayed by

BME230 Lab 5: the Electrocardiogram & Heart Sounds
Introduction
The beating of the heart is accompanied by both electrical activity and sound. The measurement
of electrical activity produced by each heart beat cycle is called the electrocardiogram or ECG.

Convolution Recitation

The goal of this lab session is to give you some insight into the form of the convolution sum and integral,
and to practice working convolutions. Convolution is a mathematical operation with a wide range of
applications; it
