Electrical engineer Eldo C. Koenig operating an AC network analyzer¹ analog computer² he designed at the Electrical Department of the Allis-Chalmers Manufacturing Company 1951.
From 1929 to the late 1960s, large alternating current power systems³ were modelled and studied on AC network analyzers or transient network analyzers. They were also ca…Read More![]()

### 🔹 What is the 74HC595?
The **74HC595** is an **8-bit serial-in, parallel-out shift register with output latches**. It allows you to control multiple outputs (e.g., LEDs) using only a few microcontroller pins. This is very useful in microcontroller applications (like Arduino) when you want to expand the number of output…Read More

At first, we sample $f(x)$ in the $N$ ($N$ is odd) equidistant points around $x^*$:
[
f_k = f(x_k),: x_k = x^*+kh,: k=-frac{N-1}{2},dots,frac{N-1}{2}
]
where $h$ is some step.
Then we interpolate points ${(x_k,f_k)}$ by polynomial
