An AM broadcast station is transmitting at its assigned frequency of 880 Khz. The carrier is modulated by a 3.5 Khz sine wave. D
1 answer:
Answer:
Transmitted frequencies are 876.5 KHz and 883.5 KHz
Explanation:
We have given that carrier frequency
And modulated frequency
We have to find the transmitted frequencies that are LSB and MSB
For finding LSB we subtract the modulated frequency from carrier frequency
So LSB = 880-3.5 = 876.5 KHz
For finding LSB we add the modulated frequency to carrier frequency
So LSB = 880+3.5 = 883.5 KHz

Answer:
The three phase full load secondary amperage is 2775.7 A
Explanation:
Following data is given,
S = Apparent Power = 1000 kVA
No. of phases = 3
Secondary Voltage: 208 V/120 V <em>(Here 208 V is three phase voltage and 120 V is single phase voltage) </em>
<em>Since,</em>

<em /><em />
The formula for apparent power in three phase system is given as:
Where:
S = Apparent Power
V = Line Voltage
I = Line Current
In order to calculate the Current on Secondary Side, substituting values in above formula,
