low-bank DTMF signal

The 20 Hz signal that rings a telephone’s bell has to have a very large amplitude to produce a loud enough bell signal. How much larger can the ringing signal amplitude be, relative to the low-bank DTMF signal, so that the response of the filter in Problem 14.51 is no more than half as large as the largest of the DTMF tones?

Problem 14.51

Design a series RLC band pass filter for detecting the low-frequency tone generated by pushing a telephone button as shown in Fig. 14.32.

a) Calculate the values of L and C that place the cutoff frequencies at the edges of the DTMF low-frequency band. Note that the resistance in standard telephone circuits is always R = 600 Ω

b) What is the output amplitude of this circuit at each of the low-band frequencies, relative to the peak amplitude of the band pass filter?

c) What is the output amplitude of this circuit at the lowest of the high-band frequencies?
