1) What's wff  and theta come from in Figure 9. Block diagram of PLL at low speed?

   

A: wff isn't been used in the actual algorithm. theta is calculated by PLL inside.

   

2)  Is there HFI demo board on sale? I want to buy one.

   

A: No special demo board for HFI algorithm. The algorithm has been widely used for washing machine, refrigerator and drone product.

   

3) The HFI code is C language or lib?

   

A: The algorithm is been implemented by C language.
