by Tarun Agarwal 9 years ago Tactile Sensor Working and Its Types The WSG-DSA is a gripper finger that integrates tactile sensing for high-resolution profile feedback during grasping. For sensing purposes, it uses a DSA9205i intelligent tactile transducer. It fits on top of the base jaws of the WSG and...
by Tarun Agarwal 9 years ago Digital Electronics: Flip-Flops Tutorial The term flip-flop (FF) was invented in the year 1918 by the British physicist F.W Jordan and William Eccles. It was named as the Eccles Jordan trigger circuit and includes two active elements. The design of the FF was used in the British...
by Tarun Agarwal 9 years ago Phase Locked Loop Working with Applications The phase-locked loop is one of the basic blocks in modern electronic systems. It is generally used in multimedia, communication and in many other applications. There are two different types of PLL’s – linear and nonlinear. The nonlinear...
by Tarun Agarwal 9 years ago Zero Crossing Detector Circuit and Working A zero-crossing detector or ZCD is one type of voltage comparator, used to detect a sine waveform transition from positive and negative, that coincides when the i/p crosses the zero voltage condition. In this article, we discuss the zero-crossing...
