Analog
electronic circuit brought revolution to human civilization. It became so
popular in early 1900 and became fully mature after 1900. The biggest discovery
in modern science is the invention of Diode and Transistor. Without this invention
it is hard to imagine tech world. This tutorial
will cover multiple choice questions in Analog Electronic Circuits. The MCQs
will cover topic such as Introduction to analog circuits, Diode and its
operations, BJT and Amplifiers, MOSFETS and circuits, Voltage and power,
Oscillators and Amplifiers, Op-Amp and its applications, Filters and tuned
amplifiers and finally Shaping and waveform generation circuit. Hope this
sample questions will be useful. If you find this tutorial helpful don’t forget
to share this with your friends. Don’t forget to justify your answers.
