RLC Circuit Analysis

By Thomas Devaraj

About this worksheet:

  • Calculates the impedances across frequencies in a RLC passive crossover network 
  • Applicable in electrical engineering, electronics and high-tech industries, speaker design 
  • Performs using Excel, frequency, resistance, capacitance, inductance, angular frequency, reactance, impedance, etc.

This worksheet using PTC Mathcad includes an example of an engineer designing a hi-fi speaker that must meet a certain frequency response. The horizontal trend must be over the whole spectrum of the audible range with a tolerance of +/- 1dB. Because at least two transducers are needed, you must look at the case in which there is both a low and high frequency driver. You can calculate the impedances of each to determine the overall frequency response.  This worksheet uses data from excel and plots the solutions.
