Possibly the lowpass enveloped matched an integrator in low freqs, then wouldn't need to apply integrator again. Maybe a lower null would match it better.

Could send raw pulse widths or could downsample before transmitting.

To do a DAC from 40kHz first could zero expand to 200kHz, and then could simulate the circuit digitally, which would generate a PWM that could then in analog domain be integrated.
