How is Miss penalty calculated in cache? You can calculate the miss penalty in the following way using a weighted average: (0.5 * 0ns) + (0.5 * 500ns) = (0.5 * 500ns) = 250ns . Now, suppose you have a multi-level cache i.e. L1 and L2 cache. Hit time now represents the amount of time […]
What is the difference between Butterworth Chebyshev I and Chebyshev II filters?
What is the difference between Butterworth Chebyshev I and Chebyshev II filters? Butterworth filter has a poor roll-off rate. For the same filter order, the stopband attenuation is higher for the Chebyshev filter. Compared to a Butterworth filter, a Chebyshev-I filter can achieve a sharper transition between the passband and the stopband with a lower […]
What does not affect stopping distance?
What does not affect stopping distance? Visibility is one of a number of factors that do not affect your braking distance per se but can inhibit your thinking distance. The longer it takes for you to spot hazards in the road, the more time will have passed before you hit the brake pedal. What will […]
What happens to the workpiece if the cutting tool is dull?
What happens to the workpiece if the cutting tool is dull? There are many effects of performing a cutting operation with a dull tool. Note that a dull tool has an increased tip radius (see Fig. 21.22 on p. 636); as the tip radius increases (the tool dulls), the cutting force increases due to the […]

What number does the Lucas sequence approach?
What number does the Lucas sequence approach? Definition. Similar to the Fibonacci numbers, each Lucas number is defined to be the sum of its two immediate previous terms, thereby forming a Fibonacci integer sequence. The first two Lucas numbers are L0 = 2 and L1 = 1 as opposed to the first two Fibonacci numbers […]
Which of the following quenching media is most severe in its quenching action?
Which of the following quenching media is most severe in its quenching action? Different quenching media have different degrees of severity. Caustics are the most severe quenchants, followed by oils, then salts and, finally, gases. Which quenching media gives the fastest cooling? Brine. Brine is a mixture of water and salt. Brine cools faster than […]
Is drag equal to weight?
Is drag equal to weight? When drag is equal to weight, there is no net external force on the object and the vertical acceleration goes to zero. With no acceleration, the object falls at a constant velocity as described by Newton’s first law of motion. Which reaches terminal velocity first? Both elephant and feather weigh […]
