Caution is better than Risk, Prevention is better than cure. using the the right tools for a job alone is not sufficient; You have to get trained and informed about its proper use and safety precautions. When we Design a Product or Develop further a design; we have to integrate Product Safety into the usage method and improve usability and safety. Product also has to be Engineered in such a way that manufacturing it does not pose hazard to the worker.
When you wish to Begin to learn Electronics, first a short study of Physics is essential, secondly some Electronics theory. Then build simple and small gadgets to learn Practical Electronics while working with Educational Hobby Circuits. Lastly to make your own product designs, a fundamental knowledge of Analog and Digital Electronics is the foundation for your next steps into Engineering a Design.
An Embedded Microcontroller or DSP system is made of Chips, Circuits and Firmware. The digital voltage levels, speed, bus width, fan out, power consumption are some factors that a designer has to keep in mind. As portable and wireless gadgets are becoming more popular, RF, Ethernet and Energy Efficient Design aspects should be studied.
Here is a complete project which will help in learning to apply the CA3140 in a small instrument that could be used in your test bench along with the oscilloscope. It is necessary to study the datasheet for understanding the device and this application with full details. A function generator having a wide tuning range is shown in Figure 10. The 1,000,000/1 adjustment range is accomplished by a single variable potentiometer or by an auxiliary sweeping signal.
Ergonomics and Manpower the Engine of Growth - A Worker in One Firm is a Customer for another Firm. Healthy and Safe Workers implies a strengthening Consumer base.Just imagine what wonders it can do for the economy, when you broaden your view, think togetherness, as a Whole; not in isolated competitive groups, not in parts.
