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)
How might you encode audio (or video) data in two packets so
that if one packet is lost, then the resolution is simply reduced to
what would be expected with half the bandwidth? Explain why
this is much more difficult if a JPEG-type encoding is used.
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

- 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.)arrow_forwardCan I at least ensure that the length of a bitstream won't rise due to my compression algorithm?arrow_forwardAudio CDs encode the music at 44,000 Hz with 16-bit samples.Would it make sense to produce higher-quality audio bysampling at 88,000 Hz with 16-bit samples?

-  There is redundancy that can occur in video that is sent over a network. Encoding techniques take advantage of two broad classes of redundancy. Name these two encoding techniques, and how each can be used for more efficient compression.arrow_forward1. Compact discs record two channels (left and right) of music at a sampling frequency of ??=44.1kHz for each channel. If each sample is encoded with 16 bits, and one byte is 8 bits, how many bytes are required to store 48.1 seconds of music? 2. Consider a system that uses 8-bit ASCII codes to encode letters. How long (in microseconds) will it take to transmit the bit sequence encoding Hello-World! if we use a bit time of 4 samples per bit, and transmit samples at a rate of 1MHz? 3. The ASCII table below gives the ASCII codes for common alphanumeric characters and symbols listed from MSB to LSB. What is the bit sequence encoding the message 113? Assume that we transmit the codes of each character in sequence with the LSB first.arrow_forwardAn analogue sensor has a bandwidth which extends from very low frequencies up to a maximum of 14.5 kHz. Using the Sampling Theorem (Section 3.3.1), what is the minimum sampling rate (number of samples per second) required to convert the sensor signal into a digital representation? If each sample is now quantised into 2048 levels, what will be the resulting transmitted bitrate in kbps? Give your answer in scientific notation to 1 decimal place. Hint: you firstly need to determine the number of bits per sample that produces 2048 quantisation levels (see Sections 2.4 (Block 1) and 3.3.2 (Block 3)).arrow_forward
- When moving images are sent across a network, redundancy is inevitable. In encoding, we employ two kinds of redundancy. With regards to compression, which of the following two methods should be used?arrow_forwardgiven me solution in computer science, . A movie was shot in 150 fps. The movie lasted for 30mins. The movie was played in a vertical and horizontal pixel of 720 × 720 respectively. The bit depth for the video was 16 bit. This same video was shot having an audio sampling rate of 44100 Mhz with an audio bit depth of 32bit. The producer of the video decided to test the quality of the audio for the movie with a surround 5.1 channel audio systemi) Calculate the audio file size in bits and explain its effect on the video file.ii) Calculate the file size of the video in Megabytes (Mb) iii) Calculate the bit rate of the video file and explain the effect of the value on processing of the filarrow_forwardWhat is a monochrome bitmap?

- Can I at least guarantee that my compression algorithm will not increase the length of a bitstream?arrow_forwardThe symbol £ is magnified and shown in Figure 1 with a grid superimposed. Figure 1 The image in Figure 1 is to be encoded and encrypted using the following steps: 1. Each of the five horizontal rows of the picture is encoded as a 5-bit binary number. White squares are encoded as Os and black squares as 1s. The horizontal rows are therefore encoded as: Row 1: 00110 Row 2: 01001 Row 3: 11100 Row 4: 01000 Row 5: 11110 2. Starting from the left, the first binary digit is multiplied by 16, the second by 8, the third by 4, the fourth by 2, and the fifth by 1. This will convert the 5-bit binary numbers to decimal numbers as shown below: Row 1: (0 x 16) + (0 × 8) + (1 × 4) + (1 × 2) + (0 × 1) = 0 + 0 +4+2+0 = 6. Row 2: (0 x 16) + (1 × 8) + (0 × 4) + (0 × 2) + (1 × 1) = 0 + 8 +0+0+1 = 9. Row 3: (1 x 16) + (1 × 8) + (1 × 4) + (0 × 2) + (0 × 1) = 16+8+4 + 0 + 0 = 28. Row 4: (0 x 16) + (1 × 8) + (0 × 4) + (0 × 2) + (0 × 1) = 0 + 8 +0+0+0= 8. Row 5: (1 x 16) + (1 × 8) + (1 × 4) + (1 × 2) + (0 × 1)…arrow_forwarda. Huffman coding assigns codes to characters such that the length of the code depends on the relative frequency or weight of the corresponding character. Thus, it is a variable-length code. If the estimated frequencies for letters match the actual frequency found in an encoded message, then the length of that message will typically be less than if a fixed-length code had been used. Due to such advantages, RadiantRay Networking Sdn Bhd uses Huffman compression technique to encode the message before transmitting over the network to its customer. Suppose the message contains the following strings "a fast runner never be afraid of dark“ a. How many bits may be required for encoding the message without using Huffman coding? b. Create an Huffman table indicating the number of character bits, frequencies and the code used in transmission of the message (space is also counted as a character) c.
