Estimating FM Bandwidth: Solved Examples
In this article, we'll illustrate the usefulness of Carson's rule for bandwidth estimation by working through a series of example problems.
Exploring the Relationship Between FM Wave Bandwidth and the Modulation Index
In this article, we'll investigate how varying the amplitude and frequency of the modulating tone impacts the bandwidth of FM signals. We'll also compare the modulation index in AM and FM schemes.
Three Methods for Estimating the Transmission Bandwidth of FM Signals
Along with introducing Carson's rule for bandwidth estimation, this article explains how to calculate the required transmission bandwidth based on either the sidebands or the total power of the signal.
Introduction to Wideband FM Signals
Learn how Bessel functions and the modulation index can help us understand the bandwidth of wideband frequency-modulated (FM) signals.
Why 50 Ohms Became the RF Standard
The history, physics, and practical trade-offs behind a number every RF engineer knows.
One of the fundamental properties of a coaxial cable is its characteristic impedance often represented by Z0. It is the value of resistance seen when looking into a coaxial cable of infinite length. The value of Z0 is solely determined by the physical construction of the cable.
