Nodal analysis can be applied to both planar and non-planar networks since each node, whether it is planar or non-planar, can be assigned a voltage. Nodal analysis is a common tool used to study the network structure of an interconnected network. It is also known as nodal correlation, nodal filtering, or edge detection. Nodal analysis is a technique used to investigate the properties of networks. It is a simple concept that can be applied to both planar and non-planar networks. In this tutorial, we will explore the techniques that are used for nodal analysis .
