The hardware complexity of both the analog and digital circuits is smaller than an equivalent DDS-based generator.HernandezL.QuesadaA.Electronics, Circuits and Systems, 1998 IEEE International Conference onL. Hernandez and A. Quesada, "Programmable sine wave generator employing a mismatch-shaping ...
There's a trade-off between the sine wave resolution (number of points from sin(0) to sin(2*pi)), output frequency range, and precision of the output frequency (e.g. we want a 20kHz wave, but we can only get 19.8kHz or 20.2kHz because the step is 0.4kHz). The output frequency ...

I am confident I am sending correct data orientation to the device via the SIF as I can reliably do things like swap twos-compliment - offset binary and physically see a sine wave input from a device change to and from the expected wave shapes. I can also physically see the output turn...
[答:David] You can use MCU/FPGA + DAC to finish arbitrary Wave Generator.The wave of the output depends on your MCU,in your MCU Rom, there should be a table of Sine wave. [2008-6-26 11:59:45] [问:mr wei] PWM输出后用什么样的滤波方式可以稳定形成DC,而且是线性。请问你们有什么什...
