Q.1 For each of the following three cases, classify if you would consider the appliance as an embedded system or not. For each case, list TWO of the features given in the descriptions that support you to classify it as or not as an embedded system. (a) An electric toothbrush that has a 8-bit PIC16F1516 microcontroller (16MHz, 8k Flash, 512 bytes RAM), a small LCD display, an i2c pressure sensor, and a motor driven by an H-bridge. (b) An iPhone 7 has an Apple A10 processor in it. This processor is a quad-core 64-bit CPU running up to 2.3GHz, with large L1, L2 and L3 caches. It also has a powerful GPU (graphics unit). (c) A microwave oven has a 8-bit PIC processor in it. This processor runs at 10MHz and the only interface is an LED display, a keypad, and some circuitry to operate the fans and magnetron
