T and π Network Trainer NV6518 has been exclusively and attractive designed to demonstrate the significance of image and characteristic impedance of T and ð-network. It can be used as a stand alone unit with inbuilt DC power supply. Various scope of learning makes the subject understanding complete. This trainer includes not only the experimental calculation of image and characteristic impedance but also verifies it by comparing the theoretical values under T and ð-networks in a sequential manner. With this, students can learn about importance of Symmetrical and Unsymmetrical networks.
