hi i have develop a circuit from glolab worldwideweb.glolab.com/glmda/GLMDA.pdf
*so surprised that i cant add link if my post < 3:-(
from the manual , it says that C4,C3,R3,R4 serve as bandpass (10Hz) as well amplifier gain, with gain 100
The problem is when i calculate the bandwith frequency using 1/(2nRC) i get different values...
and, does c4 and R4 perform low pass filter n C3, R3 perform high pass filter?So, by combining these 2 together it become bandpass filter... Pls correct me if im wrong
one more thing that make me thinking, why do we need such filter if we are using DC source....honestly, im not realy good at electronic so can some1 pls help me?:grin:
