Introduction The purpose of this blog is to design an own filter with a specific cutoff frequency by choosing one of the filter types among Butterworth, Bessel, Cheby1, and Cheby2, Elliptical filter, and its order with ideal OPAMP. Also, the implementation of the filter is given by Direct Form 1(DF1), DF2, Parallel, and other implementations….


How to Calibrate a ZED Stereo Camera

All lens have some distortion no matter how big or small, so you should correct for lens distortion by calibrating a camera in terms of software. Especially, this technique is used for robotics and the distortion effects so much while a robot is mapping some obstacles using a camera as their eyes. Today, I am…
