Abstract
A bandpass version of sigma-delta modulation is presented, with simulation results for second- and fourth-order convertors. For the fourth-order convertor operating at 8 MHz, simulations demonstrate a resolution of 16 bits over an 8 kHz band centred at 1 MHz. Applications may include analogue/digital conversion for AM radio, and digital/analogue conversion for narrowband RF systems.
