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 ...

Next-generation MOSFETs cut on-resistance

Extending Infineon Technologies’ OptiMOS 5 portfolio of power MOSFETs are 80-V and 100-V variants optimized for high switching frequencies used in synchronous rectification applications for telecom and server power supplies, as well as industrial applications such as solar, low-voltage drives, and power adapters. OptiMOS 5 devices slash on-resistance by up to 45% for 80-V parts and up to 24% for 100-V parts ...
