Four frequencies are applied at the input of a non-linear amplifier. Write down all of the frequency components at the output of the non-linear device. Write down only the first three harmonics. Frequencies of 1205Khz, 1200Khz, 1195Khz
One load absorbs 1.5kW at a 0.707 pf lagging. Determine: (a) the pf of the second load, (b) the parallel element required to correct the pf to 0.9 lagging for the two loads.
Show transcribed image text Four signals m1(t). m2(t). m3(t). and m4(t) are bandlimited to 3.6 kHz. 1.2 kHz. 1.2 kHz, and 1.2 kHz, respectively. These signals are to be transmitted using TDM.
A digital oscillator delivers two sinusoidal signals at 10 kHz and 12 kHz, sampled at 60 kSa/s. What is the minimum FFT length N that will result in a leakage-free FFT if both tones are present?
The return current is through the outer conductor, which consists of an infinitely thin cylindrical shell of radius b. Use Ampere's law to calculate the magnetic field intensity everwhere.
