(6) You are required to design a software control 4-bit successive approximation A/D converter. Specifically you are only provided with the following components: Anda diminta untuk merekabentuk penukar A/D penghampiran berturut-turut secara kawalan softwer. Anda dibekalkan dengan komponen-komponen berikut sahaja: 1. A microcomputer with 4-bit 1/0 ports/komputer mikro dengan port 1/0 4-bit. 2. A 4-bit D/A converter/ penukar A/D 4-bit. 3. A comparator/pembanding. (i) Sketch and label the block diagram of your design showing the interconnections between the essential components clearly, Lakar serta label gambarajah blok rekabentuk anda dengan menunjukkan dengan jelas sambungan komponen yang penting, (3 marks/markah) (ii) draw a flowchart to describe your control program, lakar carta alir bagi menerangkan program kawalan anda, (3 marks/markah) 5 5 (iii) assuming the input analog voltage Vin = 5 V, plot D/A output signal versus clock number in successive approximation. menggandaikan voltan input analog Vin = 5 V, lakar signal output D/A melawan bilangan jam dalam penghampiran berturut-turut.
