Yes there is, right before and after the DSP. The final frequency conversion is done with an IQ mixer and that looks like its providing a baseband I and Q output. These In Phase and Quadrature signals contain all the amplitude, frequency and phase information needed to reconstruct the signal in the digital domain. The I and Q signals are then fed to an analog to digital converter, processed by the DSP and when I say processed they are further filtered digitally in band width, demodulated, AGC is applied somewhere then a final digital to analog converter gets you the resulting processed and demodulated analog audio from the receiver.
Look at the block diagram and you will see what I described and also the lack of a hardware IF, no hardware IF filtering, no hardware demodulator, its all broad band RF until the final mix down to baseband before digitizing and DSP. Its an SDR and if the mfr wanted to and there was enough on board memory, they could diddle the internal software to give you more or different IF band widths, add another waveform (a mode like WBFM or P25 or anything else) and it would use the exact same hardware.
But there's no ADC or DAC converters, at least in the block diagrams...Mike
