This example streams input from a ADC source to a DAC.
An analog signal is acquired block-by-block into SDRAM from the ADC (an AD9244 in this example).
The frames are then output with a one-frame delay to the DAC (an AD9744 in this example).
In this example, no processing is done on the frames. They are passed unaltered.
uses the message signal X to modulate the carrier frequency Fc (Hz) and sample frequency Fs (Hz), where Fs >
2*Fc. FREQDEV (Hz) is the frequency deviation of the modulated signal.
Qpsk signal Processing Code
The DSP code should be efficient and accurate to properly demodulate the incoming signal. The DSP can be coded strictly in “C” or C-language can be intermingled with assembly code.include
