in qpsk we are using phases for representation of messages while in qam we hav amplitude levels. in qpsk 2 bits per symbol is used with four different phases. in qam depanding on type i.e 16 qam,64 qam,256 qam how many amplitude levels to be used accordingly i.e 16,64,256. sonender kumar
You are asking this question because you are trying to cheat on your homework!
Well, isn't that just a happy little question! To calculate the baud rate for a 72000 bps 64-QAM signal, you simply divide the bit rate by the number of bits per symbol. In this case, for 64-QAM, each symbol represents 6 bits (2^6 = 64), so the baud rate would be 72000 bps divided by 6, which equals 12000 baud. Just remember, there are no mistakes, only happy little accidents in the world of calculations!
In Quadrature Amplitude Modulation (QAM), the number of possible symbols is determined by the modulation order, which is typically expressed as (2^M), where (M) is the number of bits per symbol. For example, 16-QAM has (2^4 = 16) possible symbols, while 64-QAM has (2^6 = 64) possible symbols. The higher the modulation order, the more symbols are available, allowing for higher data rates but also requiring better signal quality to minimize errors.
The distance between two numbers on a number line is calculated by taking the absolute difference between the two numbers. In this case, the absolute difference between 15 and 64 is |15 - 64| = 49. Therefore, the distance between 15 and 64 is 49 units.

There is not much difference between Office 32 and Office 64 bit programs in terms of performance. However, Office 64 has a larger memory and stores more data.
There are 64 years between 1947 and 2011. To find the difference, you subtract 1947 from 2011, which gives you 64.

The difference between a 32 bit and 64 bit CPU is the speed in which a computer will read and process the information. A 64 bit CPU will read much quicker and can handle the memory usage better than a 32 bit.
