**Tutorial Electronics**. Hello, i have a cousin who is studying in us and needs help in Operational amplifiers are linear devices that have all the properties required for nearly ideal dc amplification and are therefore used extensively in signal conditioning, filtering or to perform mathematical.

Learning about basic electronics and creating your own projects is a lot easier than you may think. Operational amplifiers are linear devices that have all the properties required for nearly ideal dc amplification and are therefore used extensively in signal conditioning, filtering or to perform mathematical. Electronics is simply the use of electronic components to manipulate the flow of current to achieve a desired aim in a circuit.
