8) This describes the essential skills and knowledge and their level, required for this unit. Evidence shall show that knowledge has been acquired of safe working practices and solving problems in electronic and digital equipment. All knowledge and skills detailed in this unit should be contextualised to current industry practices and technologies. KS01-EE123A Basic electronic and digital principles Evidence shall show an understanding of basic electronic and digital principles to an extent indicated by the following aspects: T1 Fundamental concepts insulators and conductors basic electrical units and engineering prefixes voltage, current and resistance Ohm’s Law electrical power digital and analogue multimeters T2 Alternating Currents and Waveforms waveforms (sine and square wave) the AC mains supply electrical safety fuses lamps and indicators T3 Electromagnetic Waves and Signals electromagnetic waves the Radio Frequency spectrum wave propagation signals and bandwidth transmission lines and antennas harmonics T4 Capacitance and inductance inductors and capacitors T5 Electromagnetic Interference electrical noise induced currents and voltages cross-talk electromagnetic Interference T6 Batteries types of battery battery capacity care of batteries T7 Techniques in the use of analogue and digital multimeters - broad overview of electronics theory applicable to commonplace electronic and computer equipment servicing and support tasks, and includes general appreciation of the topics and concepts rather than rigorous theoretical calculations and designs T8 Analogue versus digital digital waveforms T9 Number systems binary hexadecimal binary addition and subtraction number system conversions T10 Codes ASCII ANSI error detecting codes - parity - check sums - CRC error correction T11 Basic logic AND, OR, NOT, XOR truth tables T12 Data manipulation clocks and data rates basic storage cell registers ripple counter (binary counting) shift register (serial to parallel conversion) multiplexer and de-multiplexer bus architecture - encoding / decoding - addressing methods T13 Analogue to digital conversion T14 Digital to analogue conversion - broad overview of digital electronics theory applicable to everyday computer servicing and support tasks and encompasses topics and concepts and is not for in depth theoretical calculations and designs. Also there are no specific logic gates or logic levels involved. |
