Create a 1Mhz sine wave output without any crystal oscillator in Multisim. This will be used in AM transmitter.

A 3-phase 208V line-to-line), 4 pole 1746rpm induction motor is taking 45kVA at 0.9 power factor. The total developed torque is 2000N-m and the rotational losses are 1.5kW. Determine the following: a) The rotor copper losses b) The overall efficiency c) The stator winding resistance (per-phase)

QUESTION 5:

A) Given that V_an = 230  ̶ 10^o for positive sequence voltage Y connection load, Find the phase voltages and line voltages then draw a phasor diagram to show all voltages.

B) Consider a 300 kVA single phase load with pf = 0.85 lagging and it is required to correct the pf to 0.90 leading, Find the reactive power (Qc) added after using the parallel capacitors and the value of capacitor added if V = 380 kV and f = 50 Hz.

what are the components of the reactive power compensation with description and figures?

• Describe at least two cases where you have observed the effects of light refraction besides the case of a swimming pool.
• Why the fabrication of optical fiber is a very delicate process?
• What do you understand is the "Dispersion" effect in communication fibers

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
