Circuit Theory - Essay exemplificationThe paper Circuit Theory shows and describes some figures with the two-way crossovers work. At frequencies way above the pass band, the rove of increase in attenuation is 12dB/octave at a 90 degrees phase shift which goes to clxxx degrees at very last frequencies. The rate of the attenuation here depends on the filter order, which in hug drug is determined by the number of reactive components in the ladder. For instance in our case here thither are two reactive components, hence the filter order is two and its rate of attenuation is devoted by nx6dB/octave = 12dB/octave since n=2. Its response at different values of n is as shown be commencement.A two-way crossover has a combination of a high pass and a low pass filter which could be used to drive a tweeter and a loudspeaker at the aforesaid(prenominal) time. These two could be fed from the same model of an amplifier if and only if it can accommodate the frequency ranges of both of them. H owever this is a wide range hence its impossible to come up with such(prenominal) an amplifier, hence the two-way crossover is used. With the low pass filter designed as explained earlier its high pass counterpart can be derived from it following the simple fact that their frequency response is reciprocative of one another. This means that attenuation of a low pass filter at say a frequency of w=2 is the same as the equivalent high pass at w=0.5. Deriving from this the high pass filter components are the reciprocal of the normalised low-pass filter, such that where there are capacitors in the low pass model they are replaced by inductors in the high pass model.
