Thank you for the clarification, Lyle. I hadn't seen that information anywhere before. The existing K3 manual seems quite misleading in talking about 8 bands of audio equalization. We now learn that the EQ facility allows the user to set the relative levels at 8 discrete frequency POINTS, and

In the KX3, the gain of the FIR filter at the specified frequency is set to the requested value, and a linear interpolation is performed from the next lower specified frequency. At the highest frequency, sertting, all frequencies higher are set to the requested value. The K3 operates in a

[Elecraft] Meaning of EQ bands?

2012-06-21 Thread Ian White GM3SEK
A new question, probably for Lyle to respond: How exactly are the EQ bands implemented in DSP, in terms of frequency response? Although the controls are presented in histogram form, what do the stated frequencies actually represent? Is the actual frequency response composed of overlapping
