Modify the simulation program given in Computer Example 3.4 to allow the sampling frequency to be entered interactively. Examine the effect of using different sampling frequencies by executing the simulation with a range of sampling frequencies. Be sure that you start with a sampling frequency that is clearly too low and gradually increase the sampling frequency until you reach a sampling frequency that is clearly higher than is required for an accurate simulation result. Comment on the results. How do you know that the sampling frequency is sufficiently high?
Example 3.4
The preceding example demonstrated the required amplitude response of the VSB filter. We now consider the phase response. Assume that the VSB filter has the following amplitude and phase responses for f > 0:
q1. determine the phase relation between vo and ig for the given network if vg 45sin317tq2. determine vo for the given
Find i(t), vL(t), v(t), the energy stored in the capacitance, the energy stored in the inductance, and the total stored energy for the circuit of Figure, given that vC(t) = 10 cos(1000t)V. (The argument of the cosine function is in radians.) Show ..
A proportional controller for a rotating antenna has a gain Kp of 5 in .oz/deg. The antenna was initially pointing due south but was then commanded to point southeast. a. Find the initial torque supplied to the antenna.
Estimate the approximate final speed v2 of the golf ball
A series circuit consists of a voltage source and four resistors (R1=1k-ohm; R2=30-ohm; R3=470-ohm; R4=2k-ohm). The resistor of 1k-ohm has a voltage of V1=3V across its terminals. a) Find the current out of the voltage source.
