Narrow Band-Pass Filters for Low Frequency Applications: Evaluation of Eight Electronics Filter Design Topologies (R. Attri Instrumentation Design)

Narrow Band-pass filtering techniques have been a challenging task since the inception of audio and telecommunication applications. The challenge involves keeping quality factor, gain and mid-frequency of the filter independent of each other. The critical applications require a design that ensures mid-frequency immune to the circuit component tolerances. It becomes increasingly difficult for low-frequency applications where the shift in few Hz in mid-frequency would cause desired frequencies to fall outside the filter’s bandwidth and go undetected. The selection of right topology of the filter for the best performance is the key to successful design. This book objectively compares the relative performance of none popular narrow band-pass filter topologies. The filter topologies are evaluated using a real-world practical example of designing an extremely narrow band-pass filter. The book provides guidelines for selecting the right topology for the low-frequency narrow band-pass filter.
