Picture is AM, sound is AM or FM
Liffey Sound FM was created in 2006-09.
Amber Sound FM was created on 2008-10-04.
West Sound FM was created on 1990-05-21.
AM radio is KHz FM radio is MHz AM radio can cover the world. FM radio can cover a county. AM radio is excellent in communication. FM radio is completely worthless, except for good sound quality. AM radio doesn't have as good sound quality as FM. FM is much higher on the radio spectrum than AM.
Is the secret sound the sound of someones footsteps as they walk
FM radio uses frequency modulation to broadcast sound over radio. FM radio waves are usually transmitted between 87.5 to 108.0 megahertz.
Since the signal is passed over radiowaves, you can expect to lose some sound quality depending on which FM transmitter you purchase.
It is 1600 or 180
A quick and relatively easy way to boost FM reception is to purchase and install an FM signal amplifier; These devices normally have an on/off switch, are easy to install and come with directions. However, the best way to improve FM reception is to replace your antenna and/or car radio system entirely.
easy
FM provides noise immunity, whereas AM is easily affected by noise. With FM, the amplitude of the sound is converted into a shift in frequency. So the volume is limited by the bandwidth, but the frequency of the sound can vary as much as it likes, giving a higher fidelity sound. Spikes induced on the signal usually affect the amplitude of the signal. The amplitude of an FM signal is not used in the demodulation process and is therefore immune to spikes in the signal. AM was first used in radio because it is very easy to achieve using basic components. A single rectifier only, is needed to recover the audio. FM is quite a complicated process and could only be achieved once electronics had progressed.
