The correction amplifier is included in many audio applications. Its use is mainly in the regulation of volume, height, depth, balance settings, channels, and extended versions as well as more band equalizer. There are the simpler versions such as home movies, personal computers, car. However, there are even more demanding applications, where the correction amplifier extended to listening to different bands. Already mentioned band equalizer, which is now part of almost every recording studio. Applies even when the sound of concerts. This project deals with its links with the microprocessor and then control the PC via USB. Utility sends the PC via USB management factors in the microprocessor data, which is further processed and under control of the data correction circuit amplifiers using the IIC bus.
Voltage source controlled by MCU
Požár, Marek ; Vorel, Pavel (referee) ; Friedl, Martin (advisor)
Laboratory source is basic and necessary part of almost every modern electronics laboratories. Development cannot be done without good laboratory resources. It is main function is supply stabilized DC voltage and current. It appears in a simpler version without the continuous regulation of voltage and current, with only predetermined switching voltage. Of course there are also more demanding applications, where stable voltage adjustable fluently and where is continuous of stable voltage for example LCD applications. This term project deals with a connection of microprocessor and stabilizing and regulating circuits for voltage and current of laboratory sources output. That microprocessor controls performance features by DA converter, which provide a stable output voltage which required power.
