Evaluate the use of analogue and digital electronic devices, in complex systems like a scientific calculator and an amplifier. For the calculator look at the input components such as chips (IC) on a circuit board, switches what do they do. The processor (microprocessor) chip (IC), central processing unit (CPU), what does it do. The output, display screen LCD, what does it do. The power source, batteries, lithium, alkaline. Where would you expect AND, OR, NOT, EXOR gates to be used. What are FULL ADDER/HALF ADDER circuits show the circuits. How is multiplication done. For the amplifier Look at the input, a small voltage/current is applied, uses the power supply to help to increase the input signal, via a transistor/op-amp integrated circuit (IC). Uses, to drive headphones, speakers. Types of amplifiers, Audio frequency, Radio Frequency, video amplifiers etc. Classes of amplifiers such as class A, B, C and AB.

Your family have a small house in the countryside which is not connected to the grid. The place enjoys 3.5 equivalent sun hours. Therefore, you have decided to install an off-grid PV system in the house to supply their electricity. you will be using PV modules with the following specifications: P, We may assume that the combined efficiency of the cables, the charge controller and the battery system is 90% and that of the inverter is 96%. As the house is only used at the weekend, only two days of autonomy will be needed. In this case, batteries with the following specifications will be used: capacity 100 Ah, voltage 12 V, maximum allowed depth of discharge 50%. The daily house electricity requirements are summarized in the Table. = 100 Wp, VMpP =16 V, IMpp = 6.25 A, Voc = 18 V, Isc = 7 A. %3D nom Quantity 10 Time of use (h) Type Power per item (W) 20 Load Light bulb TV DC 1.
