Recreating the THX Deep Note – Earslap. Read this blog post on how to create the THX Deep Note (the sound at the beginning of movies using THX). It involves some signal processing – see if you can do it in MATLAB. Here is professor Zucker’s implementation in shadertoy https://www.shadertoy.com/view

# Add code to Fourier Series Lab so Function Generator makes Sawtooth and Triangle wave

Right now, the signal generator is only configured to create sine waves and square waves. Code could be added to the U8903a GUI to enable the generation of triangle and Sawtooth waves.

# Build shaker table + building for E12 lab

Build a shaker table with sinusoidal input that shakes model building that is instrumented with accelerometers.

# DSP Codecs Use Beamforming to Optimize Voice Signals

Design you own beam-forming microphone array, or come up with a novel application for this integrated one. DSP Codecs Use Beamforming to Optimize Voice Signals | Embedded content from Electronic Design.

# Explore Fourier Transform and Filtering in 2 dimensions.

Explore Fourier Transform and Filtering in 2 dimensions (i.e., images).

# The hot rod.

Put a heater on one end of a metal rod, and measure, predict and model the temperature along the length of the rod.

# Compartmental modeling (physiological systems)

Read up on compartmental modeling and model some physiological system (e.g., glucose metabolism…)

# Analyze and simulate the double pendulum without the small angle approximation.

Analyze and simulate the double pendulum without the small angle approximation. Include an animation.

# Build an analog computer.

Build an electronic analog computer (a circuit analog to Simulink) using integrators and summers….

# Try to model the friction of the double pendulum experiment.

Try to model the friction of the double pendulum experiment. The friction is closer to kinetic than viscous, so you’ll need a non-linear model (either your R-K, or simulink). This has some interesting aspects to it (as friction often does).

# Develop a thermal model for a hot box.

Put a heater in a box and try modeling the temperature in the box over time.

# Develop a system to measure hand position and develop a model.

Build a small dial with a pointer and measure the transfer function of your hand as you try to follow a moving target.

# Model a spider on a spider’s web.

Try to predict the deformation of a spider’s web with a spider sitting on it – you could model the web as springs and dashpots.

# Explore the audio impulse response of various areas around campus.

Record the audio impulse response (pop a balloon) and record the audio impulse response of various locations around campus. Play various sounds through the impulse response and explore the results.

# Explore a triple pendulum system

We have a triple pendulum system – explore the modes of oscillation of this sixth order system, experimentally and in simulation.

# Get data from double pendulum using a vision capture system.

Get data from double pendulum using a vision capture system.

# Explore Filters

Explore filter types (Butterworth, Chebyshev) – try them out on the EMG data from lab – see if you can get the same results as the BioRadio software (you can also play with the filters from within their data collection software)
