🔍 Key Concepts

• RC coupling capacitor role in blocking DC while passing AC • Difference between phase relationship (0°, 90°, 180°) and simple DC level shifting • How the shaded DC component on the left of figure F compares to the pure AC waveform on the right

💭 Think About

• Look at the instant when the input waveform on the left reaches its positive peak. At that same instant in time, what is happening to the output waveform on the right? Is it at a positive peak, negative peak, or crossing zero? • Consider what a series capacitor with a resistor load does at the output for mid‑frequency signals: does it mainly change phase, or does it mainly shift the DC reference level of the waveform? • Compare figure F with figure E (transformer coupling). In both, the DC component is removed. In which one, if either, do you clearly see the waveform inverted (180° out of phase)?

✅ Before You Answer

• Verify from figure F whether the input and output waveforms reach their maximum and minimum values at the same time or at opposite times. • Check if the output waveform’s center line is at 0 V, indicating that the DC component has been removed. • Confirm whether the question is asking about DC removal or about changing the magnitude of the AC voltage, and eliminate any choice that describes a function you do NOT see in the figure.

In referring to figure "F" of the illustration, what statement is true concerning the functional purpose of the RC coupling? Illustration EL-0075

The RC coupling functions as a filter by removing the DC component from the varying DC input to produce an AC output shifted 90o from the input.

The RC coupling functions as a filter by removing the DC component from the varying DC input to produce an AC output shifted 180o from the input.

The RC coupling functions as a filter by removing the DC component from the varying DC input to produce an AC output in phase with the input.

The RC coupling functions as a voltage transformer by changing the magnitude of the peak to peak AC voltage at the output proportional to the RC time constant.
