The Bode plot of a filter. What is the voltage gain of the filter at the cut-off frequency?

Horizontal
F = 1 kHz
I = 1 Hz

Vertical
F = 10 dB
I = -40 dB

Unfortunately, without more information about the specific filter and its transfer function, we cannot determine the voltage gain at the cut-off frequency from the given Bode plot parameters.

To determine the voltage gain of the filter at the cut-off frequency, you would need to refer to the Bode plot. A Bode plot displays the frequency response of a system, showing the gain magnitude and phase shift as a function of frequency.

In this case, we are given the information about the horizontal and vertical components of the Bode plot.

For the horizontal portion of the Bode plot, we have:
Cut-off Frequency (F) = 1 kHz

For the vertical portion of the Bode plot, we have:
Voltage Gain (F) = 10 dB
Voltage Gain (I) = -40 dB

To find the exact voltage gain at the cut-off frequency, you would need to consider the gain magnitude at that frequency point on the Bode plot.
