Unformatted text preview: High-frequency corner: 2825 Hz at gain = -2.88dB (closest possible to -3.0dB) Note: Can increase steps per decade and choose a more narrow frequency sweep range to improve the measurement. For example, sweeping from 100 to 1000 Hz in 50 steps yields a data point of -2.92 dB at 302 Hz; sweeping from 1000 Hz to 10000 Hz in 50 steps yields a data point of -3.00 dB at 2884 Hz. Passband gain (move cursor to maximum magnitude value): -0.88 dB Further Exploration:...
