- 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.)a. 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. What is the total size of the massage to be sent?a.
