Figure 7 Spice Simulation of the Upper and Lower Halves of the Slider Pots. This figure consists of two graphs which have been put together to make a single figure. The horizontal axis of the graphs is from 10 Hz to 100 kHz. The vertical axis on the top graph goes from minus 1 dB to plus 13 dB in one dB steps. The vertical axis on the lower graph goes from minus 13 dB to 0 dB in 1 dB steps. Starting with the green trace in the top graph, the overall appearance of this trace is a lot like a sine wave. see text. It starts out at 10 Hz and about 0.7 dB. It rises to 4.8 dB at 30 Hz. It rises to a peak of about 12.1 dB at 60 Hz. Then descends to a minimum of about 4.1 dB at about 125 Hz. Then goes up again to a peak of about 12.2 dB at 250 Hz. Next minimum is 4.7 dB at 500 Hz. Next peak 12.1 dB at 1000 Hz. Minimum 4.3 dB at 2000 Hz. Maximum 12.1 dB at 4000 Hz. Minimum 4.1 dB at 8000 Hz. Maximum 12.0 dB at about 16000 Hz. It passes through 4.8 dB at 32000 Hz before trailing off to 0.7 dB at 100 kHz. The blue trace starts at 10 Hz and 1 dB. It is approximately a straight line from 45 Hz to 20 kHz. 3.8 dB at 30 Hz. 5.3 dB at 60 Hz. 5.7 dB at 125 Hz. 5.9 dB at 250 Hz. It holds more or less steady until about 5 kHz. Then its 5.6 dB at 8 kHz, 5.2 dB at 16 kHz, and about 4 dB at 32 kHz. The red line runs across the graph at zero dB. The lower graph is the exact mirror image of the upper one. Just read the description again but mentally put minus signs in front of all the dB values.
