37. Touch-Tone Phones On a Touch-Tone phone, each button produces a unique sound. The sound produced is the sum of two tones, given by y sin(2alt) and y= sin(2=ht) where I and h are the low and high frequencies (cycles per second) shown on the illustration. For example, if you touch 7, the low frequency is /= 852 cycles per see- ond and the high frequency is h = 1209 cycles per sec- ond. The sound emitted by touching 7 is y = sin(2# (852)r] + sin(27(1209)r]
