ELEC 242 Lab

Introduction

In Lab 9 we built the major components of our television system: the camera and the viewer. Unfortunately the viewer is directly attached to the camera and we can only view what our own camera is pointed at. We've got the "vision" but no "tele".

This week we will make the additions necessary to allow the video signal from one camera to be displayed on a different viewer. This consists primarilly of circuitry to synchronize the disk of the receiver with that of the camera so that the scanned spot will be in the same place in both the transmitted and received images.

When we're done, this is what the system will look like:

and

are the camera video output and receiver video input signals that we saw last time.

and

are the camera sync output and receiver sync input which are the major subject of today's Lab.
