Sagot :
Answer:
USB-6000
Explanation:
For this strange exercise, you must take into account two fundamental aspects of the data acquisition cards;
* The resolution of the cards, which for a 12-bit card is 2.24mV =2.24 10⁻³V , for which a card of this resolution is sufficient
In your case, the amplitude is 50 mv, which is why it is much higher than the resolution of the card.
* The sampling rate or the frequency in which the card can acquire the data, the typical frequencies go from 200 Khz to the MHz, in general a card that has more than double the frequency to be measured should be selected.
In this case the frequency of your wave is
f = 1 / T
f = 1/100 10⁻³
f = 10 Hz
therefore a low frequency card is suitable.
- The third point is the requirement that it has a USB interface, most of the card do not have it
If you check the National Instruments catalog, there are low-cost cards for example: USB-6000 of 12bits and 10KS / s the latter is the samples taken per second
