Fourier Transform of a Generic Gaussian

5 years ago

The following computation was done out of an exercise from ELEC 221 Signals and Systems. The method does require some trickery to compute, but once it's done, we have a stunning result: the Fourier Transform of a Gaussian is another Gaussian!

Result: The Fourier Transform of the Gaussian \(f(t) =...

One of the things I see many software developers use is a Mac. Even at Microsoft's own Build expo, you can see presenters use macOS to use Microsoft VS Code. This puzzled me a bit, so I did some digging. For the most part, a Macbook is an all-in-one package for a decent laptop that runs on linux. Th...

USB Serial for Blue Pill (STM32) with PlatformIO

6 years ago

The Blue Pill (STM32) can be bought very cheaply on sites like eBay and Aliexpress, but they likely do not come shipped with a USB bootloader. You are then forced to use a USB to Serial/USB to TTL to interface with the BLue Pill, and that can be a nuisance sometimes, especially since you have to cha...

When making a HTTPS request from a Java Client, the client receives a certificate and will verify the server by checking if the certificate exists in its truststore. If the certificate exists, the client will proceed the request, otherwise it will throw an exception. Even if the certificate is verif...
