Introduction

Every electronics laboratory requires some testing instruments to test the operation of devices used in a circuit to perform some particular task's. Function generator is one of them. Function generator is a most important instrument of electronic and electrical laboratories. It is used for generating signals that have different shapes and frequencies. Now a days more advanced function generators have been developed by companies. The cost of these advanced function generators is also very high so everyone is not able to purchase them like me. But now a days some cheaper function generator that have only few features are available in the market as DIY kits. XR2206 is one of them. The XR2206 has following features:

• Low cost
• Small in size
• Wide frequency range(1Hz - 1MHz).
• It can generate sine, triangle and square wave signals.
• It requires a 9V DC power supply.
• Adjustable amplitude(not possible for square wave output).
• frequency can be adjusted by fine and coarse knobs.
• frequency range can be selected by a jumper.
