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