8 bit digital firing circuit of triac
freinds, i have a doubt in the project circuit that iam doing. The project is 8 bit digital firing circuit of a TRIAC. The doubt in the circuit is
1) how the firing angle is controlled digitally and how 8 bit is controlling output digitally ?
2) what is necessity of the or gates in the way shown?
3) Why have they grounded the inputs given to DIP switch?
Please clarify my doubt as early as possible. Thanks in advance. So please analyse the circuit and reply me at the earliest.😔
