Unformatted text preview: 8 , the capacitor with a value C to be determined, and the input voltage a cosinusoid of frequency . (a) Find the frequency response of this system (b) The tweeter loudspeaker is designed to best reproduce frequencies above 2 kHz , so it is desired to build an audio "crossover" lter accordingly. Determine the value of the capacitor, C , that will give you a 3 dB cuto frequency of exactly 2 kHz . (Dont forget to convert from Hz (cycles/sec) to radians/sec in your analysis!) (c) Sketch on separate graphs the magnitude response, and the phase response, of this lter from-10 kHz to 10 kHz . (d) Show that this lter has a highpass frequency response (you can refer to your sketch(es) in Part (c) if you wish.) Page 1 of 1 by D. Jones...
