1. Calculate the CRC-8 for the following frame. Use the generator used by Bluetooth which is 0xA7 (1010 0111). That is an 8-bit value.

Message: 1100 1101 0000 0101 (This is a single 16-bit value)

2. You have received the following message, with a CRC-8 attached. The generator is 0x9B (1001 1011). Determine if it was correctly sent (division gives you a remainder of 0)

10011100001100100111000

Note: CRC-8 means that the generator is 8-bits long, and the remainder at most 7-bits

3. You have received the following message, with a CRC-8 attached. The generator is 0xA7 (1010 0111). Determine if it was correctly sent (division gives you a remainder of 0)
