Sampling data | Cypress Semiconductor
I was working onUART and just started with SPI....
In all the communication protocols, the data is sampledi.e in UART it is either 8x or 16x.
i want to know
1. How does the component decide wheteher the received data is 1 or 0( is there something like out of 8 samples maximum occurance of high voltage is decided as 1)
2. What if due to noise interference during sampling wrong values are sampled.
3. the devices are far apart and connecting the common ground is not possible...and differential data is sent.....how will the device at the other end point take this voltage level .... what will the scenario at the input of diff amp if present for amplifying data and sending to sampler..
