A few months ago, I wrote an article about a highpass filter and how it can be used for edge detection in Image Processing applications. Today, I present you an improved method to extract the edges of an image and a technique to modify the outcome in order to become more visual appealing.
Last semester, I took a VLSI class. The class included a project and a written examination. The project was on VLSI Design (duh?) and, to be specific, we had to implement a 4-bit Up/Down Counter with Parallel Input from scratch. Yes, that means we designed our own gates from discrete transistors and built our final circuit one block at a time.
Back in the 60s, communications were not as widespread as they are today. People had the radio and some early form of the television, but this is a one-way information link. If they wanted to send a message across the globe, they had to use the expensive and unreliable telephone. This is why the hobby of Amateur Radio was then, what the Internet is today.
When I decided my career path to be that of RF Engineering, I had no doubt it was going to be difficult but I never suspected how much digging in other branches of science and math is required.
