UPenn Projects

DigUro (ESE 350: Embedded Systems)

I could write an entire blog on this project. In fact, I did!


Docking Station (ESE 215: Circuit Theory)

The goal was to take the output from a normal 1/8" aux phone output and filter the treble and bass into two separate speakers. We were given target cutoff frequencies (Treble: 8k-10kHz, Bass: 50-250Hz), and a transformer (to step the wall AC voltage from 120Vrms down to 12Vrms).

Filter Design

Input: 0 to ~300mV from aux cable. Output 1V/V gain with the following pass frequencies: 8k- 10k (treble) and  50-250Hz (Bass)

Power Supply Design

Input: 120Vrms from Wall. Output: +12V at Vp and -12V at Vn

Amplifier Design

Input: Vmusic from the filter component. Output: Voltage across speaker (denoted with 8Ω resistor).
