Question
Q1: Choose the correct answer from the following: 1. For an open circuit (OC) load, the value of the reflection coefficient equal to (a) 1 (b)-1 (c) infinity (d) 0 2. If the voltage of the carrier(Voc) is greater than from the Voltage message (Vm). Therefore the value of the modulation index (m) would be, (a) greater than 1 (b) less than 1 (c) equal to 1 (d) infinty 3. For ZR #Z0, the total reflection is occurred when the load is short circuit. the value of the voltage and the current Exets Ixsts (a) Ext=max, Ixt = 0 (b) Exal = 0, Ixal = max (c) Exet = max, 1x==max (d) Ext=0, 1x1 = 0 4. The electrical distance (as a function of the wavelength) between two successive minimum voltages in the standing wave pattern of a TL is equal to (a) 0.2 (b) 0.25 (c) 0.5 (d) 0.75 5. The highest power efficiency can be achieved in the conventional DSB-AM modulation (b) 33% is: (a) 23% (c) 53% (d) 73%
