"limitation on the magnitude of phase angle of the load" is a long winded way to say that the load shall be resistive with maximal +/- 3° phase devitation. Sacred fussiness!
Phase angle can mean phase between two nodes in a circuit. Could be just
at load and V, I as Klaus points out, or between V between two nodes, such
as phase angle thru an amplifier circuit. Or between V at one node and I at
another. Its a relative observation/measurement. Very useful in control systems
stability analysis, design of low distortion circuits, in communications for
pulse response........
Here is measuring phase angle of a non ideal Capacitor :
I am answering this question as shown in the image. I had no trouble deriving \$\frac{V_{out}}{V_{in}}\$ in the first question(answer is \$\frac{j\omega L}{R + j\omega L}\$ I also had no trouble...
I am fairly green to control theory. I am trying to reproduce the Open loop transfer function of the LT1X28 op amp in mathematica. I want to get the poles and zeros from the following plots and pro...
