HW # 5 1. Speakers are designed to have an equivalent impedance of 8 Ω over the audio frequencies (roughly 500 Hz – 20 kHz). For the circuit below: a. Determine the impedance, Z match , such that the Thevenin impedance of the circuit is equal to the impedance of the speaker, Z load at 5 kHz. Include Z match in the circuit when answering the remaining parts of the question. b. Calculate the value of the Norton current source c. Write an equation for the voltage transfer characteristic, H(f). d. Calculate the power dissipated by the load impedance with respect to the power generated by the voltage source in dB at 500 Hz, 5 kHz, and 20 kHz. 2. Find a) the Thevenin and b) the Norton equivalent circuit with respect to the boxed component for the circuit shown below.
