    VisiGoth, thanks for your response. I wrote a matlab script that converts the serial bitstream into decimals representing 10bit numbers and then plots it. The number is unsigned with the LSB as the leading bit. the thing is, plotting the numbers (10bit stream converted to decimals) i don't get...

    FFT on 10Bits

    Hi, I am using a logic analyzer to view the output on a 10bit ADC and have to verify that the ADC is working correctly by taking the output and reconstructing the input 20kHz square wave by using FFT in matlab. I am having trouble performing fft on a series of 10bits at a time instead of the...
