Hello,
I am asked to design a bandpass filter with the following spefications:
Q=1
passband gain (Ko) =1
fo=5MHz
I have to use RC, CR, LC, CL circuits to build the filter.
I built an RC and CR circuit, each have fo=5MHz, and cascaded them. so, the bandpass filter now have fo =5MHz, but the bandwidth is too big. How can I reduce it ?
I tried to cascade the circuit with itself (several times) so that the roll off increases, and as a result the bandwidth decreased to 5MHz, but the circuit became too big. Is there an efficient alternative way to reduce the bandwidth ?
About the Ko, I will use an amplifier at the output, so it should not be a problem , I hope.
This circuit is not going to be implemented, it is only going to be simulated using Multisim.
Thanks in advance.
