Final answer:
To calculate the magnitude ratio for a 60 Hz component of a signal, additional information about the filter's response at that frequency is required. The magnitude ratio is the output amplitude divided by the input amplitude, and it would be obtained using the filter's transfer function.
Step-by-step explanation:
To find the magnitude ratio for a signal component, specifically the 60 Hz component with an amplitude of 75 mA passing through a filter, we would need additional information about the filter's characteristics at 60 Hz. The magnitude ratio, also known as the gain of the filter, is the ratio of the output amplitude to the input amplitude at a given frequency. Without details on the filter's response, we cannot provide a numerical answer. However, typically this would involve calculating the output of the filter using its transfer function and the given input signal parameters.
The magnitude ratio for the 60 Hz component of the multi-frequency signal can be calculated using the formula: Magnitude ratio = (Amplitude of the component) / (Amplitude of the original signal). In this case, the amplitude of the 60 Hz component is given as 75 mA. Since the amplitude of the original signal is not provided, we cannot calculate the magnitude ratio without this information.
