In such devices, input analog signal firstly comes to analog-to-digital converter and then transferred in digital form to microcontroller, microcontroller performs processing according to program and transfers data to digital-to-analog converter that reproduces processed analog signal. Thereby, after signal went through device it becomes processed. </em></p><p><em>High-speed devices, development of software and hardware solutions for constructing microconverters in modern information and telecommunications systems were described.</em></p><p><em>There performed overview and analysis of microcontrollers and their architecture, peripherals, characteristics. These parameters were analysed in terms of use for signal processing.</em></p><p><em>We provided implementation solutions of analog-to-digital conversion using embedded peripherals of microcontroller and external modules of analog-to-digital conversion. Also, successive approximation conversion was described.</em></p><p><em>We provided implementation of digital-to-analog conversion using pulse-width modulation and second-order Butterworth filter.</em></p><p><em>Analysis of signal processing operations in digital form using microcontroller was performed.</em></p> ER -
