Question
a. What frequency is one octave above $5 \mathrm{kHz}$ ?b. What frequency is one decade below $10 \mathrm{kHz}$ ?c. What frequency is two octaves below $20 \mathrm{kHz}$ ?d. What frequency is two decades above $1 \mathrm{kHz}$ ?
Step 1
One octave above a frequency means doubling the frequency. So, one octave above 5 kHz is 5 kHz * 2 = 10 kHz. b. One decade below a frequency means dividing the frequency by 10. So, one decade below 10 kHz is 10 kHz / 10 = 1 kHz. Show more…
