How many bits are needed to digitally record 90 seconds of your favorite music tune? The sampling rate commonly used for music is 44.1 kHz (i.e. 44100 Hz). Each sample is represented using 16 bits. Note that music is usually recorded in stereo, requiring hence twice the number of samples that would be needed for a non-stereo recording of an audio signal

How much space would you need to store a 10 min song that has been sampled at 44.1 kHz, with each data point stored on 16 bits, in stereo (assume no compression).
A computer system uses 9 bits to store numerical data using signed 2's complement format. Assume that the OCTAL values of X = (235)8, Y = (413)8 what is the result in decimal for X + Y note : if the result is negative add a minus sign ex: -124 Answer:
The modulus for the field GF(25) is x5+x2+1 and its elements are all five-bit strings. Calculate each of the following and enter your answer in exactly five bits (Example, 01101). 1. 11111 + 00001 2. 00011 x 00011 3. 01100 x 01100
Manchester encoding guarantees frequent clock synchronization by changing signal values. What is the maximum number of bits which may be encoded without a signal change? (Note: The way this question has been asked. you are not to include the bit which includes a signal change in your count)
If we record a song that is one minute long using 16 bits for each sample and is sampled at 44.1 KHz in mono channel, without any metadata or compression, how large would the file be? Express your answer in MB. Show you work. (Note that 1KHz means 1000Hz while 1K means 1024 (and IM means 10242) for capacity calculations.)
Example: 1.7 .given the two binary numbers x=1010100 and y=1000011, perform the subtraction(a) x-y; And (b)y-x, by using 2's complement.
A video frame displayed onscreen consists of many pixels, with eachpixel, or cell, representing one unit of video output. A videodisplay’s resolution is typically specified in horizontal and verticalpixels (such as 1920 3 1080), and the number of pixels onscreen issimply the product of these numbers (1920 3 1080 5 2,073,600 pixels).A pixel’s data content is one or more unsigned integers. For ablack-and-white display, each pixel is a single number (usuallybetween 0 and 255) representing the intensity of the color white.Color pixel data is typically represented as one or three unsignedintegers.When three numbers are used, the numbers are usually between 0 and255, and each number represents the inten- sity of a primary color(red, green, or blue). When a single number is used, it represents apredefined color selected from a table (palette) of colors.Motion video is displayed onscreen by copying frames rapidly to thevideo display controller. Because video images or frames require manybytes…
