Test Pattern Generator

1
Test Pattern Generator

• Student Gabriel Horner
• Supervisor Paul Maley
• Mentor Alain Guy

Goals To build a test pattern generator and
learn practical skills for building circuits.
2
Theory

• Electron beam(s) are deflected by vertical and
  horizontal coils.
• Magnetic coil Converts voltage signal to
  magnetic fields to deflect beams

3
Additive Primaries and Shadow Mask

• One slot of shadow mask to one triad

4
Scanning

• Vertical scan frequency, horizontal scan
  frequency 25625 15.625 KHz
• Interlaced scanning reduce bandwidth

5
TPG Circuit
6
Clock Signals
7
Monitor Circuit
8
What did I learn?

• Circuit design principles
• Reinforced analog and digital theory
• Testing and debugging circuit
• Manual skills soldering, scraping copper
• Shaping a signal

9
TPG in Action

• Hopefully!
