THE SOLUTION TO SOME VEXING INSTRUMENTATION CIRCUIT PROBLEMS
M OST solid-state electronic circuits normally operate in a low voltage environment, and may be seriously harmed - even destroyed - in a high voltage circuit. Several such situations corne to mind quickly. One example 18 the analogue seetion of a computerized power mains monitor system. These circuits measure the AC voltage and current, and then pass the data to a computer.
