Question
If there are multiple excitations at different frequencies, how can one compute the output phasor response? EXPLAIN!!!
Take the average of all different frequences and use the average in the phasor circuit.
Take the maximum of all the frequenceis and use the maximum in the phasor circuit.
Use superposition to consider one source at a time.
Take the minimum of all the frequenceis and use the minimum in the phasor circuit.
a.Take the average of all different frequences and use the average in the phasor circuit.
b.Take the maximum of all the frequenceis and use the maximum in the phasor circuit.
c.Use superposition to consider one source at a time.
d.Take the minimum of all the frequenceis and use the minimum in the phasor circuit.
Explanation / Answer
If there are multiple excitations at different frequencies, use superposition to consider one source at a time because for each frequency, the impedances of elements like capacitor, inductors changes. So the net impedance of circuit chages with frequency.
Hence, we need to find the output for multiple excitations at different frequencies by using superposition.
Therefore the correct option is (c).
