WebThe bandwidth is the difference between the half power frequencies Bandwidth =B =ω2−ω1 (1.11) By multiplying Equation (1.9) with Equation (1.10) we can show that ω0 is the geometric mean of ω1 and ω2. ω0= ωω12 (1.12) As we see from the plot on Figure 2 the bandwidth increases with increasing R. Equivalently the sharpness of the resonance … WebHere we use the simulator to sweep frequency (rather than DC voltage). The result is a plot of behavior vs. frequency. If we plot magnitude and phase of gain vs. frequency, we have a Bode plot. S5-5.
