The following examples use this approach in a matched-filter design ... notch transfer function. The use of two biquadratic equations allows us to fine-tune the transfer function through the filter ...

Our physics expert picks his top-five equations, plus a scheme to supply US power needs with a bucket of baseballs. Thanks, ...

Neal Iverson started with two lessons in ice physics when asked to describe a research paper about glacier ice flow that has ...

While entangled photons hold incredible promise for quantum computing and communications, they have a major inherent disadvantage. After one use, they simply disappear.

Part 2 of this DI series presents a device that allows you to play with and display live SDR signal spectrums with negative ...

We have looked at how to solve equations with one unknown value, but what happens when there are two unknown values? An equation with two unknown values will have infinitely many solutions.

If an equation can be rearranged into the form \(y = mx + c\), then its graph will be a straight line. In the above: \(x + y = 3\) can be rearranged as \(y = 3 - x\) (which can be re-written as ...

It is shown that if one chooses the field points appropriately, the set of finite difference equations is applicable for a boundary condition involving perfectly conducting surfaces. An example is ...

(For more examples of how not to write help requests, see Section 3.2 of this document.) We could poke in the dark, but it would probably be more productive if you gave us a bit more detail explaining ...
