In addition to the properties and usage of basic discrete components (still
very important) and the appreciation of fundamental principles (from an introductory mathematical perspective) of electronics, there is an increasing interest in the use of integrated circuits, especially at low and intermediate signal levels. It is seldom necessary to be an expert at the inner workings of these ICs, but the ability to understand their data sheets and how to employ and interconnect them is a skill that is very useful. We probably could be tested a little regarding the basic usage of certain kinds of ICs such as opamp, multiplier and DSP types. Bill W0IYH "nntp.aioe.org" wrote in message ... I suggest that it still lies in the areas of LC filters, resistor networks and individual transistor (or valve) operation. Because, although the bulk of our circuit complexity will soon lie in a single DSP chip, the interfaces to that chip, to us at the baseband end and then to the antenna at the RF end, still depend upon traditional electronic (pre-IC) practice. How, then, can it be possible to issue Ham Radio licences to those who cannot tell one end of a resistor from the other? How, then, can it ever be possible to issue Ham Radio licences to those of 6 years of age who lack the mathematical capability to understand the evaluation of resistances in parallel? The answer is, that it cannot be possible, and that licences issued to such people are CB licences, no more, no less. Syllabi for Ham Radio exams should resort to the traditional subjects of familiarity with elemental electrical and electronic components together with a modernised examination of the ability to write software and understanding of DSP theory. |
