What is the lowest order of the Butterworth?

What is the lowest order of the Butterworth? What is the order N of the low pass Butterworth filter in terms of KP and KS? Explanation: We know that, [\frac{Ω_P}{Ω_C}]^{2N} = 10^{-K_P/10}-1 and [\frac{Ω_P}{Ω_C}]^{2N} = 10^{-K_S/10}-1. Which is better FIR or IIR? The advantage of IIR filters over FIR filters is that IIR filters usually […]

Can a translation undo a reflection?

Can a translation undo a reflection? No. The translation followed by a reflection would put a figure in a different location in the plane when compared to the same reflection followed by the same translation.

Is it more energy efficient to boil water?

Is it more energy efficient to boil water? An electric stove requires more energy and time to heat up, thus it takes longer to heat the water inside the kettle. However, an electric stove is more efficient in delivering energy to the kettle. Using boiling water and vinegar removes mineral deposits that reduce its energy […]

Is pigment ink better for heat transfers?

Is pigment ink better for heat transfers? So after going by all the characteristics and differences in the inks, it is advised to use Pigment ink for heat transfer paper. The reason for using a pigment ink over the regular dye ink is that the pigment ink doesn’t fade quickly. How do you make a […]

Which WiFi frequency is best?

Which WiFi frequency is best? Ideally, you should use the 2.4GHz band to connect devices for low bandwidth activities like browsing the Internet. On the other hand, 5GHz is the best suited for high-bandwidth devices or activities like gaming and streaming HDTV. What is the advantage of having WiFi in your car? Benefits of car […]

Why do wheels have friction?

Why do wheels have friction? A wheel or ball on a surface is held there by static sliding friction. In order to start the rolling motion, a force or torque must be applied to the wheel. The force of the static sliding friction prevents the wheel from sliding and thus initiates the rolling motion. Is […]

Why are Fraunhofer lines missing?

Why are Fraunhofer lines missing? Fraunhofer lines are dark absorption lines in the solar spectrum that can be seen when sunlight is passed through a prism to separate it into the colors of the rainbow. These dark lines were segments of colors missing from the complete spectrum. … Can you touch dry ice? Dry Ice […]
