dear Prahlad J. Purohit
please read starting from very first post of this thread we are not discussing here about circuit, we are tring to find noise genrated only due to mcu not any other part of the circuit,if you want that i should mark supply ground pins of 8052 every body knows about them,any way please tell me what more detail i should add, i will try to do that but let me remind again we are discussing here only noise due to mcu part with no other component connected although i have posted whole design. on same pcb i mounted only L1,L2,SUPPLY CAPS,104,7805,CRYSTAL and RESET circuit nothing else to measure the noise level. thanks kuldeep |
