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 an  amplification stage that can limit the generation of the signal. A possible analy ...

OscilloPhone: Use your Smartphone as an Oscilloscope / Signal Generator

Oscilloscopes and Signal Generators are two essential electronics devices to create and test electronic circuits. Unfortunately, these devices are very expensives for students starting electronics, or makers who want use electronic circuits in their creations just once... The idea of my project is to rethink your smartphone as a portable, powerful and secured platform, able to simulate an oscilloscope and a ...

BoardMerge- The command line single page PDF merge utility for PCBs

Toner Transfer Method.. is no doubt sheer Awesomeness. With just a few steps you can have your prototype in your hands without waiting for weeks for the fab house to deliver. Certainly relieves me of a lot of anxiety. I even made this Open Agitator a while back to help me ease out the etching process. I usually (used to) print my designs on the glossy photopaper near my college where there is a usual hub of ...
