TRANSMISSION THROUGH A NETWORK 437V (t) .Into column V enter the value ofK2Trmv57.3 X — cos vt sin degrees.v Q,V. Enter the A m's obtained in step C into column VI.Example: From step C, A 2= 17.8 + jO. This column is the samefor all the work sheets.VII. Multiply the A m's, column VI, by the cosine of the angle in columnV and enter the result into column VII.Example: For m = 2,(17.8 +j'0) cos 53.8 degrees = 10.5 + jO.VIII. Multiply column VII by the cosine of the angle in column IV andenter the result into column VIII.Example : For m = 2,(10.5 + y0) cos 17.1 degrees = 10.0 + jO.IX. Multiply column VII by j sine of the angle in column IV and enterthe result into column IX.Example: For m — 2,j (10.5 + y0) sin 17.1 degrees = + /3.1.X. Enter the B m 's obtained in step C into column X.Example : From step C, B 2= — yi4.3. This column is the samefor all the work sheets.XL Multiply the B m's, column X, by the sine of the angle in column Vand enter the result into column XI.Example: For m = 2,(0 - yi4.3) sin 53.8 degrees = - ill.5.XII. Multiply column XI by the cosine of the angle in column IV andenter the result into column XII.Example: Form = 2,(0 — j'11.5) cos 17.1 degrees = — j'11.1.
