- 1. 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.1024K words need at least how many address bits?Determine the gi, pi, Pi, and Gi values of these two 16-bit numbers: a: 0001 1010 0011 0011two b: 1110 0101 1110 1011two Also, what is CarryOut15 (C4)?
- (Non-negative signed binary numbers) What happens if all of the zeros on the left side of a non-negative signed binary number are removed? In general, how does one convert a non-negative N-bit signed binary number to an M-bit unsigned binary number, where N ≤ M?3. Consider the generator, G = 10011, and suppose that D has the value 1010101010, and number of CRC bits is r = 4. What is the value R?In other words, how many address bits does 1024K words require?
- How many bit strings of length 10 contain a) exactly four 1s? b) at most four 1s? c) at least four 1s?Consider a SEC code that protects 8 bit words with 4 parity bits.
