Currently, signal and image processing is the swiftly enlarging field in both industry and educational sectors. For the past three decades, due to the semiconductor technology evolution, the digital signal processing (DSP) theory and DSP processors take part in an essential vital role in almost all fields of science, engineering, and technology. Due to the massive growth of computer industry and information technology, there are ample software simulation tools made accessible for beginners to research any field of science and engineering. J-DSP editor is one such Internet-based tool, which is entirely written with the help of Java applets. Our work concentrates primarily on the elementary theory on DSP using J-DSP environment blocks. Mainly, the basic discrete-time system difference equation, discrete Fourier transform (DFT) of a sine function, DFT of the Fs/2 sequence, a digital notch filter, and a group delay in the finite impulse response (FIR) filter are exemplified using the on-line J-DSP simulator. Finally, the survey results from the scholars’ community who attended the training course on DSP were obtained as feedback. © 2019 SERSC.
