dear all,
i get this design from internet **broken link removed**
1. Fin (frequency input on LM2907, Vout= Vcc x Fin x R1 x C1) is electrical frequency (in term i dont use magnetic pick up)?
2. what is the function of schmitt trigger ?
3. how to determine the value of each electronic component (R, C ) in schmitt and amplifier?
thx for helping
