Active All-Pass Crossover Networks with Equal Resistors and Equal Capacitors
[Engineering Report] Two all-pass crossover networks are described. One is a three-way network with filter sections (high-pass, band-pass, and low-pass) of order four, the other is a four-way network with filter sections of order six. The two crossover networks are realized as active filters using only equal resistors and equal capacitors. This configuration ensures that even though the available standard components may differ from the theoretical values, the pass-band amplification and the quality factor are kept constant. All filter sections have identical crossover frequencies and phase responses. Transient response and polar response for the two filters are examined.
