Hello,
I want to take one real time speech signal using a microphone then sample that analog signal and i want to convert those samples into digital signals using DPCM technique,by writing code in VHDL.
Is it possible to giva analog samples as input to FPGA?
Please help me as soon as possible.
Thank you,.
 

No. FPGAs only have discrete inputs (ie. each pin is '1' or '0')
You will need an external ADC to input values to the FPGA.
 

Thank you,
But I know that input to the DPCM are sampled pulses ,but my question is that will fpga detect those samples ,that is if we want to give these samples to the input pins of fpga,how should i interface them.
Suppose if input sample value is 3.2,will fpga recognizes it or considers it as simply logic'1'.
Please reply me as soon as possible,I am in great need of it.
 

You need an external ADC. The ADC will give the FPGA the number 3.2, assuming you connect all of the pins. how you connect it is up to you.
