Decompose using relationships 3 S(+) = 50 sin 3 (500...
Steps
"Disassemble in another way."
f(+)= 50 Sin³ (500+)
Step 1
To decompose f(t)=50 Sin³ (500x+), use trigonometric
indentity for Sin³ (e)
Sin³ (0)- 3 Sin (e)-Sin (30)
4
Step2: Apply indentity to f(t).
f(+)= 50 Sin³ (500+)
= 50. 3 Sin (500+) - Sin (3*500π+)
= 50.

6) The principal of DIT hire you to design PBAX with 120 phones. Assuming the number of call
is 3/hour/line, the average call duration is 4 minutes, and 55% of all call are made external via
a T-1 trunk (24 channels) to the PSTN. Determine carried traffic and channel usage.

Supply frequency is 50 Hz. a. Let the current drawn from the source before and after introduction of the capacitor be 1₁ and 12 respectively. Take the source voltage as the reference and express 11 and 12 as vector quantities in polar form. b. Obtain the capacitor current, Ic = I2 − I₁, graphically as well as using complex number manipulation. Compare the results. c. Express the waveforms of the source current before (i₁(t)) and after (i2(t)) introduction of the capacitor in the form Im sin(2лft + 0). Hand sketch them on the same graph. Clearly label your plots. d. Analytically solve i₂ (t) - i₁ (t) using the theories of trigonometry to obtain the capacitor current in the form, ic (t) = 1cm sin(2´ft + 0c).
