Hardware & Design

Preface
This series is aimed at providing tools for an electrical engineer to analyze data and solve problems in design. The focus is on applying linear algebra to systems of equations or large sets of matrix data.

Introduction
This article will demonstrate the use of Leontief Input-Output Models. This can be used to analyze macroeconomic models of production.

Introduction
This article will demonstrate the use of matrix algebra to solve for equilibrium in systems. This is common in network flow, economics and electrical circuits (current and voltage analysis). We will apply exact and least squares solutions.

Introduction
The time has come for a new home theater. It took 15 years to build the first one and as consequence some of the equipment is so old it is not completely compatible with the newer equipment. There has been significant progress in the audio and video quality that is available, even in the last two or three years, that it's well worth it to upgrade the experience. In addition, innovations have brought more connectivity options and home (IoT) integration will bring a more seamless, enjoyable experience.

I learned a lot in my first experience in a leadership role. This list, by no means exhaustive, are the learnings I took away from the experience:

Process for determining wireless bandwidth requirements. Should be agnostic to frequency, band or protocol. It should accommodate interoperability of multiple transmitters/receivers in the environment and inside the product.

The first thing to understand is your use cases. Once you understand what your product is supposed to do the protocols and bands required usually follow directly due to the need to be compatible with 3rd party hardware.

Introduction
This is a basic outline for determining minimum CPU core, core mix and core frequency and also minimizing power consumption.

Define High Level Use Cases
First define what tasks your CPU will perform. This will usually be something like a certain number of computations per second, minimum frame rate in a game or video play back or web pages served.

Determine Design Constraints

Under specified datasheets and lack of understanding of ESD protection has made picking diodes a hit or miss scenario. This article will lay out a method to make your diode selection much more successful.

What is not covered:

• Lightning strike protection
• System level design

Choosing your ESD diode will require simultaneously solving the following four requirements:
