The strength of a signal can vary across its frequency range due to factors like signal attenuation and the receiver's sensitivity, and it may change due to the Doppler effect if there is relative motion between the source and the receiver.
Step-by-step explanation:
The question pertains to signal strength across a frequency range, suggesting a subject matter related to Physics, specifically within the realm of wave properties and behavior. The strength of a signal typically does not remain constant throughout the entire frequency range; various factors can affect this, such as medium properties, the transmitter's power, the environment through which the signal travels, and the receiver's sensitivity.
Signal strength can diminish due to the phenomenon known as signal attenuation, which increases with distance from the source. Also, the received signal frequency may drift or change due to the Doppler effect if there is relative motion between the source and the receiver. In practice, the strength of a signal and its frequency range can determine how well a signal can be received and processed, which is crucial for applications like radio telescope observations.
Regarding the electric potential and signal properties like its continuity or channel width, all these factors are essential to determine the signal's quality and the power distribution over the frequency range.
