Explanation & Answer

Name Instructor Course Date Writing about electronic components Introduction The Samsung Galaxy Pocket is an Android Smartphone that was released by Samsung Electronics in April 2012. The phone supports both 2G (GSM) and 3G (HSPA) networking technologies. It also uses a TFT capacitive touchscreen and supports up to 32GB of micro SD card. It uses an 832MHz ARM 11 processor and has support for Wi-Fi, Bluetooth, GPS, radio and micro USB 2.0 communication parameters. Other sensors that are incorporated in the smartphone include the accelerometer and the compass. It is a low-end market smartphone that is designed to enable target consumers to enjoy similar features of high-end smartphones. This device is mainly used for communication purposes which include making calls, texting, social media and internet browsing. It can also be used for gaming, entertainment (listening to music and watching videos) and also taking pictures among others auxiliary uses.

A flip-flop is essentially a circuit that operates as a bistable multivibrator which has two stable states. It, therefore, forms one of the fundamental building blocks of digital electronics extensively used in communication systems such as computers and smartphones where it is used to store data. The D-latch is made by substituting the SR inputs of a standard SR flip-flop with and by using a NOT gate as shown below. This way the latch does not respond to Data inputs (D) when the input clock (E) is low and, therefore, the outputs remain in their last state. This latch eliminates the ‘invalid’ states problem presented by SR latches. A D-latch is commonly applied as a 1-bit memory circuit. A multiplexer is a combinational logic circuit that has several inputs and only one output. Depending on...
