6 5. Signals through systems. Consider the following input-output data for a particular acoustic system. Frequency (Hz) Input (dB SPL) Output (dB SPL) 500 50 0 500 60 10 500 70 20 500 80 30 1000 50 30 1000 60 40 1000 70 50 1000 80 60 2000 50 50 2000 60 60 2000 70 70 2000 80 80 4000 50 10 4000 60 20 4000 70 30 4000 80 40 5.1. Make a table showing output level as a function of input level (different columns) and input frequency (different rows). 5.2. Plot input-output functions for each frequency on decibel/decibel coordinates. 5.3. Plot output level as a function of input frequency for different
