What is Sound
... The physical properties of an object can also be determined by sounds the object makes. When a ball is dropped onto a soft surface, it makes a different sound than when it is dropped onto a hard surface. As you walk across the floor you can hear the change in the sound of your footsteps when you cro ...

... 3 (a) About AM radio An AM (amplitude modulation) radio signal is a superposition of a high frequency wave (100’s to 1000’s of kHz) called a carrier wave (this is the “RF” signal) and a signal in the audio frequency range (only about 100 Hz to 7.5 kHz for the AM band in Australia). The carrier frequ ...

Mathematics of radio engineering
The mathematics of radio engineering is the mathematical description by complex analysis of the electromagnetic theory applied to radio. Waves have been studied since ancient times and many different techniques have developed of which the most useful idea is the superposition principle which apply to radio waves. The Huygen's principle, which says that each wavefront creates an infinite number of new wavefronts that can be added, is the base for this analysis.
