Signal Generation with MATLAB. Example of DTMF in telephony

In mathematics a signal is a real function of a real variable f(t). In electronics it represents the evolution of a voltage (or a current) over the time and depends on the performances of the stage of the amplifier. Through a memory buffer, samples move to a digital-to-analog converter that produces a voltage signal, after

Logic PCB Business Card

About I’ve seen PCB business cards for a few years now on Hackaday, and I figured it was time to design one of my own. Most PCB business cards involve a microcontroller. I wanted to do something a bit different, so my card performs its intended function strictly with digital logic gate and D-type flip-flop

Humidity sensor using 8051

The communication protocol is explained as follows. The MCU (microcontroller unit) first sends a low signal of width 18mS to the DHT11. After this signal, the MCU pulls up the communication line and waits for the response from DHT11. It make take up to 2. to 40uS. Then the DHT11 pulls down the communication line

3D Print the Ultimate Helping Hands for a PCB Workstation

I am the Senior Analyst of the Electronic Forensics Unit of the Carabinieri (Italian Military Police) and I deal with technical investigations on seized electronic devices. I spend most of my day in a well-equipped electronic laboratory, but I was lacking a tool for performing technical assessments on printed circuit boards (PCBs). I needed a way to
