Question

In an audio system, one typically uses different speakers for different frequency ranges. A typical example is the high-frequency signal( below ~ ) going into a regular speaker. The circuit that spits the signal between the speakers is known as a cross-over network. Design a cross-over circuit that can passively split the signal into the two ranges listed above and drive the speakers. It is typical to choose the resistors in these networks to be around $10\Omega$ .

Answer 1

This problem can be solved using the concept of high pass and low pass (liters It is given that high frequency signals (above 10 k H z) go into a whereas low frequency signals (less than 10 k H z) go into a regular speaker clearly, the requirement is to design a high pan filter and a low pan filter having cut off frequencies = 10 k H z . The cross over network consists of the designed H P F and L P F . Cross over network schematic/block diagram For the design, let us take R = 10 Ohm (given in the question) Let us design a R C high pass filter with f_c = cut off frequency = 10 k H z R C high pass filter The transfer function of this H P F is v_1 (s)/v_2 (s) R/R H/0 s T . F (transfer function) = R C s/R C s + 1 = R c j
