Hi,
I have a question regarding 0.1uF bypass ceramic caps which are used in power supplys and amplifiers so that eliminate the noise in high frequncies.
I want to know if it is enugh to use them in power supply unit (in parallel to big electrolyte caps) or they must be used near the power amplifier chip (LM3875) too? My circuit uses an op-amp (TL072) too, so is it enough to just use 2 of 0.1uF caps in power supply unit or I should use 2 on power supply and 2 on poer amplifier and then 2 on op-amp power rails? (if I use 6 of them then all are in parallel but in differnt places on the circuit). So what is the best method to go with?
Thanks
