As limestone, calcium carbonate is a biogenic rock, and is more compacted than chalk. As marble, calcium carbonate is a coarse-crystalline, metamorphic rock, which is formed when chalk or limestone is recrystallised under conditions of high temperature and pressure.
Definition: A wavefunction is a function describing the probability of a particle's quantum state as a function of position, momentum, time, and/or spin. Wavefunctions are commonly denoted by the variable Ï.
An arbitrary waveform generator (AWG) is a piece of electronic test equipment used to generate electrical waveforms.These waveforms can be either repetitive or single-shot (once only) in which case some kind of triggering source is required (internal or external).hese can include standard waveforms such as sine, square, ramp, triangle, noise and pulse. Some units include additional built-in waveforms such as exponential rise and fall times, sinx/x, and cardiac. Some AWGs allow users to retrieve waveforms from a number of digital and mixed-signal oscilloscopes.
