In addition, DAMA is measuring a modulation in the dark matter wind, but COSINE is looking for an absolute rate for how fast it's moving—mostly because their "dirtier" crystals makes it more ...

Modulation is fundamental to electronic communications ... We can think of i(t) as controlling the inphase (cosine) portion and q(t) controlling the quadrature (sine) portion. Summing these together ...

Several years of data will be needed before the annual modulation claimed by DAMA/LIBRA can be totally confirmed or refuted." The COSINE-100 detector is made up of eight thallium-doped sodium ...

In this initial study, the researchers found no excess of signal in its data, putting DAMA’s annual modulation signal at odds with with results from other experiments. COSINE-100 scientists noted that ...

Sarsa says the challenge will then be to determine what is actually causing the annual modulation observed by DAMA. COSINE-100 has been taking data since 2016. Located in South Korea, that ...

modulation and demodulation. Guess what? We can do that with a spreadsheet. The first step is to generate a reference clock for the carrier. You’ll need a cosine wave (I) and sine wave (Q).

The chip includes full data filtering before modulation using a root raised cosine filter with an alpha (α) of 0.2. Sinc filtering is optional. The interface to the system microcontroller is ...
