A designer, needing to provide a unity-gain buffer, considers the use of the circuit topology shown in Fig. 2.19 on page 84 of the Text. However, the amplifier he has available has an open-loop gain of only 10. What closed-loop gain would the simple circuit produce? His boss suggests that he consider the circuit of Fig 2.16 on page 82 as a solution. As well, she requests that the smallest resistor used be 10 Id). What design would result?
Show mathematically that the spectrum of a sampled signal is a periodic version of the spectrum of the continuous-timesignal. Write the solution neatly into your learning journal.
A real estate firm evaluates incoming selling agreement forms using the single sampling plan N=1500, n=110, and c =3. construct the oc curve using about 7 points.
Coils are available which are rated at 4 volts and 5 amps. For the same number of coils to be used for both machines determine the type of armature winding for both machines, number of coils for both machines and kW rating of both.
