Unwanted
signals in electrical systems frequently overpower the desired signal. In an
attempt to increase the ratio, the desired signals are amplified
proportionately to the undesired ones. Frequency selective circuits, often
known as filters, can be used to separate desired signals from undesirable ones
as signals can be identified by their frequency characteristics. Analog filters
are available in both active and passive varieties, each having unique
properties. A first order band pass active filter is developed and
characterized in this study. The Operational Amplifier (OP AMP 741) is the
active element in this case. With the Band Width (BW), Cut-off Frequencies (FL
and FH), Center Frequency (FC), and Quality factor (Q) provided, the Transfer
Function (TF) equation is generated and defined.
