- Determine the frequencies (in kHz) at the points indicated on the plot in Fig. 22.104(a).
- Determine the voltages (in mV) at the points indicated on the plot in Fig. 22.104(b).
(a)
The frequencies at the points indicated in the plot
Answer to Problem 1P
The frequencies at the points are
Explanation of Solution
Given:
Formula used:
The frequency at the point is calculated by
Calculation:
The distance of the first point,
The distance between two vertical axes is
The value of the first point,
The value of the first point is
The values of the second point is,
The value of the second point is
Conclusion:
Thus, the value of the first point is
(b)
The voltages at the points indicated on the plot
Answer to Problem 1P
The voltage of the top point is 527.5mVand the bottom point is 181.7mV
Explanation of Solution
Given:
Formula used:
The voltage at the point is calculated by
Calculation:
The total length of the vertical axis is,
Using a scale on the vertical axis, from the plot, we can find that the top and bottom points are at a fractionof total length of the vertical axis from the bottom.
The voltage value of the top point is
The voltage of the top point is 527.5mV
The voltage value of the bottom point is
The voltage of the bottom point is 181.7mV
Conclusion:
Thus, the voltage of the top point is 527.5mVand the voltage of the bottom point is 181.7mV
