What is dB? How to Calculate dBm, dBc, dBi, and dBd, and What Are Their Differences?

This article explains dB as a logarithmic unit for ratios, using 10log for power and 20log for voltage/current. It defines dBm against 1 mW, dBc against carrier power, dBi against isotropic antenna, and dBd against dipole (dBi minus 2.15). Understanding these units and calculations enables accurate analysis and design of electronic and communication systems.
