Define the term “fixed, long-lasting permissible current”. What parameters are important to calculate it?

Design and simulate a Wein bridge oscillator that will oscillate at 2 kHz

please use online multisim

Code in Matlab for a low pass filter and a high pass filter. Each filter must show the frequency response (magnitude and phase) in graphs properly labelled.

Design hexadecimal to 7 segment by doing its truth table, its Boolean expression using karnaugh map and then expressing it using logic gates.

please this is the second time I post this question, the first time was answered as BCD to 7 segment which is not what the question is

How is the active power regulated in a synchronous generator?

Give examples of 3 distinct types of filters (band pass, high pass, and low pass). Create a diagram and a statement of the characteristic frequency scale of each in terms of the component values in the circuit.

a) Describe how each of the following can be achieved

i. controlling a DC motor with pulse width modulator.

ii.controlling a stepper motor that has a built-in controller.

The test results for the approximate equivalent circuit of a three-phase induction motor are shown below.
No-load test: equivalent applied voltage 120 V, input current 5 A, equivalent input 480 W
Restraint test: Applicable voltage 20V, input current 40A, equivalent input 480W

Determine the equivalent circuit constants of Rc, Xm, Rs + Rr, and Xs + Xr
when friction and wind losses are ignored.

Answer - 30Ω, 40Ω, 0.3Ω, 0.4Ω

How many passwords are possible?

Passwords must:

• be more than 8 characters long but no more than 30
• Use lower case, upper case, a number, and a special character [like ~ ! @ # $ % ^ & * ( ) _ + = ? > < . , / ]

A mathematical expression is fine.
What kind of PMF will be used?

Explain the operation of the isolation amplifier. Design a circuit that takes an input voltage and outputs a scaled differentiated version of the input minus a scaled version of the input, at the output of the circuit

1. An LED is connected to PORTB.5 of ATmega328 microcontroller.
Write a C Program that toggles LED after 0.5 Seconds. Assume XTAL = 16MHz.
To generate this delay use Timer 1 CTC (Clear Timer on Compare match) mode
Programming.

2. Write a program to generate a square wave of frequency of 250 Hz with 50% duty
cycle on PORTB.5. Assume XTAL = 16MHz.
Use Timer 2 Normal Mode Programming.

3. Write a program using 16-bit timer to generate a square wave of frequency 100Hz
with 70% duty cycle. Assume the crystal frequency is 16 MHz.

a 240v, 4pole shunt motor running at 1000 r.p.m gives 15 hp with an armature current of 50 A and field current of 1 A. the armature winding is wave connected and has 540 conductors. the armature resistance is 0.1 ohm and drop at each brush is 1v. find (i) useful torque, (ii) the total torque (iii) useful flux per pole, (iv) iron and friction losses

Briefly describe the classification of three main groups of magnetic materials, namely Diamagnetic, Paramagnetic and Ferromagnetic, in accordance with their relative permeability,??.Define remanent flux density and coercive field intensity, use sketches if necessary.
