This repository contains coursework and projects from ECE-291: Sophomore Electrical Engineering Projects at The Cooper Union. The course focuses on analyzing and constructing complex electrical systems while reinforcing key engineering principles.
- Electrical Engineering Principles – Frequency response, noise, feedback, loading, and interfacing.
- Analog Circuit Design – Construction and testing of amplifiers, oscillators, RF/opto-electronic circuits, and power circuits.
- Signal Processing – Understanding heterodyning, envelope detection, and frequency modulation.
- Systems Engineering – Development of a testbench, performance analysis, and proper documentation.
- Lab Instrumentation – Hands-on experience using oscilloscopes, multimeters, function generators, and other tools.
The primary project for this course involved designing and constructing a Theremin, an electronic musical instrument controlled without physical contact. The Theremin operates based on frequency modulation, where hand proximity to an antenna alters capacitance, affecting oscillator frequency and producing an audible tone.
- Oscillators and Filters – Generate and refine the signal for audio output.
- Envelope Detectors and Amplifiers – Extract and amplify the amplitude envelope of the signal.
- Voltage Dividers and DC Blocking Capacitors – Stabilize the signal and remove noise.
Below are the key project files displaying the Theremin circuit design:
