I want to build this Arduino DDS waveform generator. A Chebyshef lowpass filter with a cutoff at 12 KHz is required to filter out the 32KHz sampling noise.
The inductors are 4.7mH. Now in the photo, one can see, what I assume are Magnetic Core 4.7MH Radial inductors.
I would like to know if I can use Axial inductors instead?
Will the performance of the Chebyshef filter be the same or degraded?
I have no implementation, or design, specific reason for doing this, apart from cost. This question is similar to Axial inductor vs winding inductor, but the application (frequency range) is different, Audio (KHz) rather than FM (MHz), so I was not sure if that would affect the answer.
