Hi!
Does anyone knows what can cause aliasing effect on a signal sent from UART?

Ok. My circuit basically consists of a ADC_DelSig that send the signal to a UART. The UART data is collected on my computer and then plot in a python program. The signal ploted should be equal ( or pretty similar ) to the input signal. The problem: the signal shape only is correct in certain frequencies.

So probably the sampling frequency is too low with regards to the signal you are sampling. Are you sure you can send out data over the UART fast enough not to be a problem?
