Question 20 (1 point)

The ________ circuit overcomes the problem of false switching caused by noise on the input(s).

A) Schmitt trigger

B) input noise eliminator

C) differentiator

D) input buffer

Confused on this one, mainly the wording. Books states a Schimtt trigger is built in a comparator for hysteresis which helps with noise, but a schimitt triiger is not a "circuit" from what I gather in the text. Out of all the options there, the only one the book refers to as a "circuit" is a differentiator. But it states that is noisy which the question reads from what I gather stops/overcomes the noise.

The other two options are not noted anywhere in the chapter.

My reference material is from Electronic Devices by Floyd 10th Ed Chapter 13. Any help will be appreciated. Thank you.

Ex. 830. Design a proportional controller (Kp) cascaded with the plant:
  (s+12)/( (s+ 3) (s+ 7) (s+15) ) within a unity feedback system
  so that the dominant poles result in a 36% overshoot step response.
  Find Kp, zeta, wn, wd, Ts, Tp, the error constant (Kp_error) and corresponding
  SS error.  Note: Kp_error is different from Kp in the PID-TF. ans:8

Describe a case study of an electrical safety incident. Enumerate the Engineering, administrative and PPE solutions with reference to
evidence-based approaches in the literature. Ensure to add the references and relevant standards.

Imagine a ball heated to a temperature T. This Ball emits thermions with a current density at the surface given by C , which is proportional to AG(Richardson's constant) and proportional to W(Work function) .
a) Using charge conservation,find the current density at any distance 'r' from center.
b) Using continuity equation, find the charge density p(r,t) at time 't' ; t > 0 and it is given that p(r,t=0) = 0.
c) By solving Maxwell's equations, also find the electric and magnetic field vectors .

PLC systems

We have three different motors to work at an irrigation facility. We can only use a START button to run the system and a STOP button to stop the system.

System Conditions to Work:
*When we pressed START button first motor has to work non-stop, after 25 seconds second motor has to work non-stop and first motor has to keep working at this time. 40 seconds after second motor starts we also need third motor to START in this time first and second motors has to keep working by the way. 60 seconds after third motor starts all motors have to STOP together.

a) Write all the buttons, motors, relays and other components and their names on PLC program as a list.
b) Draw input/output connections as a schema and write names of included components.
c) Draw LADDER diagram of this program.

Could you please write this program on PLC system without using TIMER, paper or a screenshot is pretty enough but I would love to see screenshot if its possible. Thanks in advance. Stay safe!

Three equal impedances, (8+j6) ohms are connected in wye across a three-phase, three-wire supply. The symmetrical components of the phase A line voltages are:

Va0 = 0

Va1 = 220 + j 28.9 V

Va2 = -40 - j 28.9

If there is no connection between the load neutral and the supply neutral, Calculate the symmetrical currents of line a,b, and c.

a three-phase bipolar motor of 10.72 [HP] has an efficiency of 80% when working at full load at 2700 (rpm), if it is connected to a network of 440 (V) at 50 [Hz] calculate

b.) Engine displacement.

c.) rotor frequency at full load.

d.) If the kilowatt hour costs $ 185.39. The money saved in energy consumption if the engine works continuously for three years and is replaced by an engine with 97% efficiency?
