What is the transfer function of Butterworth low pass filter of order 2? Second Order Butterworth Filter Transfer Function: 2.78. At the cut off frequency fH, the gain is 0,707 Af i,e. 3 dB down from its 0 Hz level. After, fH ( f > fH ) the gain rolls off at a frequency rate […]
Is Travelling salesman problem NP-complete?
Is Travelling salesman problem NP-complete? In fact, TSP belongs to the class of combinatorial optimization problems known as NP-complete. This means that TSP is classified as NP-hard because it has no “quick” solution and the complexity of calculating the best route will increase when you add more destinations to the problem. What is the difference […]
Will soffit vents prevent ice dams?
Will soffit vents prevent ice dams? Houses with good attic ventilation generally do not experience ice dams, and the physics are quite simple: By circulating cool outside air in the attic space (or in the rafter spaces just below the roof deck), the roof surface remains below freezing and cannot melt the snow on the […]
How do you find the voltage across a capacitor in series?
How do you find the voltage across a capacitor in series? Two or more capacitors in series will always have equal amounts of coulomb charge across their plates. As the charge, ( Q ) is equal and constant, the voltage drop across the capacitor is determined by the value of the capacitor only as V […]

What are the 5 stages of a project?
What are the 5 stages of a project? Developed by the Project Management Institute (PMI), the five phases of project management include conception and initiation, planning, execution, performance/monitoring, and project close. What is Project Scheduling What are the various project scheduling? A project schedule is a timetable that organizes project tasks, activity durations, calendar start […]
How does a cylinder cushion work?
How does a cylinder cushion work? When the cushion spear enters the cushion seal, the air exiting the cylinder is trapped, causing it to compress. This provides a resistance force that decelerates the piston. The cushion seal collapses when air coming through the adjacent port is introduced, allowing for a fast breakaway. What is the […]
How do you find velocity with net force?
How do you find velocity with net force? Net force = force minus body weight. Acceleration = net force ÷ body mass (body weight ÷ the acceleration of gravity [9.81 m/s/s]) Velocity = acceleration × time. What is the difference between force and velocity? A force pushes or pulls on an object, but velocity is […]
