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 […]

Summarize, or have students summarize, the lesson. We can sequence rigid motions. What does translation do to an image? Translation […]

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 […]

How should you approach a dock when there is a strong wind blowing away from the dock? If the wind is offshore (blowing away from the dock), you should approach the dock at a 20 to 30 degree angle. A bow line is passed ashore and secured. In boats with an outboard, or inboard/outboard engine, […]
