A 3-phase, 4-wire distributor supplies a balanced voltage of 400/230 V to a load consisting of 8 A at p.f. 0-7
lagging for R-phase, 10 A at p.f. 0-8 leading for Y phase and 12 A at unity p.f. for B phase. The resistance
of each line conductor is 0.4 2. The reactance of neutral is 0.2 2. Calculate the neutral current, the supply
voltage for R phase and draw the phasor diagram. The phase sequence is RYB. IN

P.6.3-7 The Fourier transform P(f) of a the basic pulse p(t) used in a certain binary communication is shown in the figure below: P(f) 1 0.5 0 f₁ = 0.8 √₂ = 1.2 f, MHz (a) From the shape of P(f), explain at what pulse rate this pulse would satisfy Nyquist's first criterion. (b) Assuming that the pulse is a raised-cosine pulse, find its rolloff factor. (c) Find p(t) and verify that this pulse satisfies Nyquist's first criterion in the time domain. (d) Show how rapidly the pulse decays as a function of t, (i.e., what power of t does the envelope obey for large time values).arrow_forwardDon't use ai to answer I will report you answerarrow_forward
