EE 443 Lab1

Problem 1

Status: In Progress

Complete:

• Tone generation
• GUI
• Confirmed by auditory observation (earphones/speakers)
• Confirmed ability to change codec sampling rate

Incomplete:

• Check with oscilloscope
• Rigorous debugging (e.g. break points, watch variables)

Problem 2

Status: Completed

Complete:

• DIP switch control of sine wave line output
• DIP switch control of LED inidcators

Problem 3

Status: Completed

Complete:

• DIP switch control of line output channels
• DIP switchh control of LED indicators

Problem 4

Status: In Progress

Complete:

• Table lookup for sine wave
• Function generation of multi-component sinusoidal signal
• Three-parameter controls as global variables

Incomplete:

• GUI with dial control and plot (link to global variables)
• Confirmation with oscilloscope

Problem 5

Status: In Progress

Incomplete:

• Amplitude Modulation (AM) of input speech signal (real-time with microphone)
• GUI for speech input and modulated speech output
• Headphone confirmation for speech input and modulated speech output

Notes: see /CD/code/chapter_13/ccs/AMtx/ISR_Table.c for how to do AM (textbook chap. 15.4 in 3rd ed. and chap. 13.4 in 2nd ed.)
