Why do we use a scale of 0.1 for drawing Bode plots?

10. A low-pass-filter has a cutoff frequency of 24 MHz. What is the fastest rise time that a rectangular wave that will pass through the filter can have?

4.) Given the following LRC circuit (L = .012 H, R = 8 ohm, C = 2 F, w = 2*60*pi), Vmax = 100V. A.) Draw a phasor diagram of the circuit. B.) By what degree does the voltage source lead or lag the current? C.) What frequency of the voltage source is necessary to reach resonance?

You are building a Nyquist plot from a Bode plot of a system L(s) and came up with the following information: omega 0.01 0.5 0.8 1 1.3 2 10 Mag (dB) = MaB 25.4 dB 23 dB 20 dB 18 dB Mag (gain) = 10 14.13 11.22 10 4.47 Mab 20 Angle (degree) -180° -177⁰ -178° -180° -184° -195⁰ -248° -20.6 dB If L(s) has no poles on the imaginary axis, how many clockwise encirclements of -1+j0 does the Nyquist plot have? (If counterclockwise, use negative values.)
