Consider 256-QAM. How many bits does a symbol (i.e., a constellation point) represent? If a 2000 baud line is used, then what would the i) baud rate, and ii) bit rate?
Consider 256-QAM. How many bits does a symbol (i.e., a constellation point) represent? If a 2000...
Data are sent over a channel using 8-QAM with the signal constellation shown below. The pulses are rectangular, and a new pulse is generated every T seconds. 2.A Re -2A 2.A -2.4 How many bits of information are conveyed on each pulse transmission? a) b) Find the average power in the transmitted signal g(t) in terms of A

If a hash function reduces 264 bits to 256 (28) bits, how many collisions can be expected for any given input? Why does that number of collisions not undermine the purpose of a hash function, namely, to demonstrate that it is unlikely that an undetected change can be made? (Computer Security II)
How many bits does it take to represent 5,000 things?
How many select bits and how many data bits does a 4x1 multiplexer have? What does it mean? (i.e. what does a 4x1 multiplexer do? )
a. Consider a 2048-row NOR decoder. To how many address bits does this correspond? How many output lines does the decoder have? How many input lines does the NOR array require? How many NMOS and PMOS transistors does such a design need? of the tree column address bits are involved? How many levels of pass gates are used? How many pass transistors are there in total?
In quadruple precision floating point, the exponent has 15 bits, and the mantissa or significant has 113 bits. How many decimal places accuracy does that give us, and approximately what is the largest value we can represent?
In a von Neumann architecture, groups of bits have no intrinsic meanings by themselves. What a bit pattern represents depends entirely on how it is used. Consider the following bit patterns expressed in hexadecimal notation. 8D28000C16 1) What decimal number does the bit pattern represent if it is an integer? 2) What decimal number does the bit pattern represent if it is an unsigned integer? 3) If the bit pattern is in an instruction register, what MIPS instruction will be...
Question 4 (1 point) How many bits do we need to represent the decimal number 359 in binary? Convert this answer to binary. 1001 1010 1100
8. (6 points) Consider a RAM array that has a 16 bit word and an 11 bit address. The SRAM cell is about 1.5 times wider than it is tall i.e. the wider direction is along the word line). To make the RAM array as square as possible, how many address bits should be decoded into word lines and how many should be used to select the bit lines. Show your work

1. How many bits are required to represent a waveform in 4000 discrete levels? 2. An audio CD can contain 80 minutes of stereo (two independent) audio tracks. Each track is sampled with 16-bit samples at 44.1 kHz. How much audio information, in bytes, is stored on an audio CD? 3. Assume a 4-bit successive approximation A/D with VREF+ = 4V and VREF– = 0V. Calculate the 4-bit output code (in hex) if the input voltage is 1.8V. 4. A...
