Timeline:
00:00:00 Introduction
00:01:12 Approach
00:01:56 Decibels (dB) and why they are used in wireless/radio frequency (RF) engineering
00:03:32 Working with decibels
00:03:42 Decibel equivalents of selected common ratios
00:04:42 Rules for calculating using decibels
00:05:41 Converting decibel values to ratios or absolute quantities
00:07:27 Example 1: Working with dB: Addition replaces multiplication
00:08:38 Example 2: Working with dB: Subtraction replaces division
00:10:29 Example 3: Working with dB: Multiplication replaces exponentiation (raising a number to a power)
00:13:12 Tables of decibel equivalents of ratios or absolute quantities, generated from the numbers and rules that we learned
00:15:34 Example 4: Simple wireless/RF signal power calculation using dB, including conversion of result to absolute quantity in watts
