Hi all, In one of my problems there is a question with a plot of the transfer function magnitude versus frequency. In the graph I notice that the magnitude of the transfer function is greater than 1. This is confusing as I thought that filters are not able to increase the magnitude of the output signal with respects to the input as they are only able to attenuated the amplitude or change the phase of the signals. Also to strengthen my case, as the transfer function is H(f) = Vout∠θout / Vin∠θin, shouldn't the magnitude of the transfer function always be less than or equal to 0.
