What are Electronic Instruments? – Definition & Examples

In this topic, you study the definition and examples of electronic instruments.

Electronic Instruments use semiconductor devices (diodes, transistors etc.), which have excellent time response and they work without any noise or pollution. In electronic devices, the only movement involved is that of electrons hence the “response time” is very small due to the negligible inertia of electrons. The Cathode Ray Oscilloscope (C.R.O) (See Fig. 1.), the much used electronic instrument has a time response of the order of 10-10 seconds.

The “transistorized power supplies” are available which provides constant voltage supply to the electronic instruments; it reduces errors. Moreover, very weak signals can be measured after increasing their value by “amplifiers”. The electronic instruments can measure audio. video and microwave signals. Moreover, the instruments are light, compact and consume little power. The field of space communication today is totally dependent on electronic instruments, These instruments make it possible to build computers, which require very fast time response which is only possible through electronic devices.
