Initially, we used BPSK for a certain transmission. However, we then found that the bandwidth of BPSK is too wide for our channel. If we are willing to reduce distance, d, by a factor of no more than 25, what is the minimum bandwidth we can have if we were to use M-PSK under these constraints? Note that in order to answer you need to find M = 2 N. Submit all your written work by tomorrow 8 AM on Canvas.

How do we use the sumif formula (when dealing with different formats) ?

Acomputer has a two-level cache. suppose that 60% of the memory references hit on the first level cache, 35% hit on the second level, and 5% miss. the access times are 5 nsec, 15 nsec, and 60 nsec, respectively, where the times for the level 2 cache and memory start counting at the moment it is known that they are needed (e.g., a level 2 cache access does not even start until the level 1 cache miss occurs). what is the average access time?
