There are commercial software, special hardware and special instruments for that (network analyzer can usually do that on radio frequencies), but I wanted something that uses the hardware I already has.

I just noticed that MIDI turned 30 years ago just a short time ago. This 31.25kbd 10-bit, 16-channel network is still very much in use today, 30 years after its official 1.0 specification release in August 1983. I forgot to say “Happy Birthday MIDI” at the right day.

My main was to use Elisa Viihde service also with my Rasberry Pi connected to monitor (I already had set-top-box and I →
I just wrote how to Turn a Tablet into a Signal Generator. In addition to generating signals, a tablet can be used as audio signal analysis. Typically the only way to get sound into those tablets and smart phones is through built-in microphone, which can be limiting. Here are some Android software for audio signal →
Signal generators are a handy thing to have around the lab. In recent years these lab tools have not only decreased in size but also in cost and the result has been a plethora of portable versions that now exist on the market. In addition to full equipment it is nowadays possible to use a →
