Alat Bantu Pengajaran Interaktif Teknik Digital Berbasis Web

Karnaugh Map (K-map), a method to simplify the logic equations in a logic circuit, was a compulsory topic on Digital Electronics\u27 subject, yet the learning process in TE-PNJ was still done manually. Therefore, the result of this research was a web-based software which was used as an interactive tool for teaching K-map. Furthermore, the main purpose of that tool was so that the learning process becomes more attractive, easily understood, and interactive for the students. Besides that, a web-based programming was applied to build that so it was considered as an open source application. More over, It could simplify logic circuits with 2 to 4 input variables and DON\u27T CARE conditions. In addition, it could display both input and output logic equations and also number of logic gates (AND, OR and NOT) contained in each of those logic equations. Keywords: K-map, variable input , DON\u27T CARE conditions, logic gate

Analisis Penerapan Metode Konvolusi Untuk Untuk Reduksi Derau Pada Citra Digital

Noise in digital image processing is a disorder caused by deviations of the data received. There are three types of noise, Additive, Gaussian and Speckle. Currently, there are many methods for reducing noise in digital images. One method that can be used for reducing noise is convolution method, which consists of Low Pass Filter, High Pass Filter, Median Filter, Mean Filter and Gaussian Filter. This research will analyze an output by applying the convolution method for noise reduction with various parameters such as histogram, Timing- Run calculation and SNR calculation. Noise reduction will be imposed on the three types of noise. Keywords : digital image, noise reduction, convolution method, histogram, Timing-Run, SNR
