Comparison of Huelsmann Basic Biquad with View to the Decrease of the Attenuation over the Transient Frequency of the Operational Amplifier
Original language description
The signal processing at discrete time requires an aliasing filter at the input and a reconstruction filter at its output. In this paper, selected basic structures of biquads are described and compared with a view to the decrease of the attenuation over the transient frequency of the operational amplifier. Concretely, low-pass and band-pass Huelsman (i.e. multi feedback) structure are confronted with the limits of a real operational amplifier. Firstly, the reasons of the decreasing of the attenuation are explained theoretically. Secondly, these conclusions are verified by simulations. These simulations were performed by spice-like circuit simulator MicroCap version 10.
