Aragonite and calcite are polymorphs of calcium carbonate. It is harder than calcite (3.5 to 4, rather than 3, on the Mohs scale) and somewhat denser, but like calcite it responds to weak acid by vigorous bubbling.

Wavetable Synthesis Definition - Wavetable synthesis is a method for generating sounds from signals of a digital nature. The technique stores digital sound samples from various sources, which can later be modified, enhanced or combined for reproducing sounds. Wavetable synthesis is considered one of the oldest methods for generating sounds from computers. It differs from simple PCM sample playback because wavetable synthesis relies on looping over the buffer instead of simply a read once method.
A demodulator is a circuit that separates the Amplitude Modulation (AM), Frequency Modulation (FM) and Quadrature Amplitude Modulation (QAM) signals from the countless radio waves in our atmosphere and decodes the information from the carrier. demodulator may be used with a walkie talkie. A demodulator is typically known as a radio tuner. AM radio stations on a car radio might come in and out of tune as the car passes telephone poles. CB radios often use a demodulator.
