This paper describes our efforts to include a hands-on component in the teaching of core concepts of digital signal processing. The basis of our approach was the low-cost and open-source “Stanford Lab in a Box.” This system, with its easy to use Arduino-like programming interface allowed students to see how fundamental DSP concepts such as digital filters, FFT, and multi-rate processing can be implemented...
In this paper, microcontroller based automatic door open system has been developed. The system is developed as speech recognition circuit where programmable voice is used as reference. Programmable means trained voice has been used for identification of authorized and unauthorized person. As software part, MATLAB GUI interface has been used to record authorized voice, and to synthesize the recorded...
This study describes the performance results on testing MatLab applications using the parallel computing and the distributed computing toolboxes under different platforms with different hardware and operating systems. Each trial was executed keeping the hardware fixed and changing the operating system to obtain unbiased results. To standardize the benchmarking test, Fast Fourier Transform (FFT), discrete...
