Hello guys,
I have several questions regarding the bellow heart rate meter circuit:
Fast heart rate meter using CD4518 CD4046 CD4511 - Free Electronic projects & 8085 projects
Here are my questions.
1: is it a practical workable circuit? The provided info about it are very limited!
2: what is the functioning of the 4046 PLL there in the circuit?
3: Where are those D1 till D7 elements? and where are the sensors in the circuit?
Thanks in advance.
