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:

  Threats associated with a business

Reflect upon the strengths, weaknesses, opportunities and threats associated with a business that you are familiar with (one you work at, one you completed your assignments on, or one you have just acquired knowledge about).

  Find how much coffee has spilled out of the beaker

During an all-night cram session, a student heats up a 0.491 liter (0.491 x 10- 3 m3) glass (Pyrex) beaker of cold coffee. Initially, the temperature is 19.7 °C, and the beaker is filled to the brim.

  Determine the maximum current and time at which it occurs

Determine (a) the maximum current and the time at which it occurs; (b) the settling time; (c) the time t corresponding to the resistor absorbing 2.5 W of power.

  What is the limit on leakage resistance for the capacitor

The dielectric materials used in real capacitors are not perfect insulators. A resistance called a leakage resistance in parallel with the capacitance can model this imperfection. A 150-F capacitor is initially charged to 100 V.

  What would make the pll converge in frequency and phase

A clever student notices that a high constant loop gain would make the PLL converge in frequency and phase. Rather than use an amplifier with infinite gain the student decides to just use an unstable filter.
