Hardware-software complex for studying of digital filters

This work describes the hardware-software complex that is used in educational process for students of technical specialties to study the principles of design and software implementation of digital filters. Paper describes a programming part of the complex which allows calculating the coefficients of different digital filters. The possibility to transfer these coefficients to the microcontroller using UART interface is presented. The hardware part of the complex is presented by signal generators with different shape of signals (triangle signal with variable frequency, sinusoidal signal with variable frequency, sinusoidal signal with addition of noise). Experimental results of practical implementation of designed complex using STM32F4DISCOVERY board based on STM32F407 microcontroller are shown in the paper.
