1. Sound moves through what medium?
Sound travels in mechanical waves. A mechanical wave is a disturbance that moves and transports energy from one place to another through a medium. In sound this energy transfered through vibration in a medium. Types of medium include gases, liquids and solids.We use bits to measure the sample size of sound.2. What unit is used to measure sample size?
Bits are used to measure sample size.
3. What unit is used to measure sampling rate?
Sample rate: The rate at which the samples are captured or played back, measured in Hertz (Hz), or samples per second. An audio CD has a sample rate of 44,100 Hz, often written as 44 KHz for short. This is also the default sample rate that Audacity uses, because audio CDs are so prevalent.
FM (frequency modulation) is a broadcasting mode in the VHF (very high frequency) broadcasting bands. It provides a high quality analogue signal, and is relatively free from static, in which the frequency of the transmitted wave is modulated or varied in accordance with the amplitude and pitch of the signal. The operating frequency is expressed in megahertz (MHz).
Digital TransmittingDigital radio is the next generation of radio. It is a revolutionary audio broadcasting technology, which dramatically improves sound quality, and will enable you to receive value added radio services for free.
From this information I found you can clearly see that Digital Radio will provide the most best quality in sound and that to for free!
4. Compare the quality of AM, FM and Digital radio.
AM (amplitude modulation) is a system of radio transmission in which the carrier wave is modulated by changing its amplitude. The operating frequency is expressed in kilohertz (kHz).FM (frequency modulation) is a broadcasting mode in the VHF (very high frequency) broadcasting bands. It provides a high quality analogue signal, and is relatively free from static, in which the frequency of the transmitted wave is modulated or varied in accordance with the amplitude and pitch of the signal. The operating frequency is expressed in megahertz (MHz).
Digital TransmittingDigital radio is the next generation of radio. It is a revolutionary audio broadcasting technology, which dramatically improves sound quality, and will enable you to receive value added radio services for free.
From this information I found you can clearly see that Digital Radio will provide the most best quality in sound and that to for free!
So from this informqation we can see that sound is recorded as a sample rate in Hertz.
