4.3 Alice and Bob decide to use the following modulation scheme to map the bits to the inter-packet delay. A delay of 0.25 is used to encode a bit 0 and delay of 0.75 is used to encode a bit 1. Write a Python code that will generate the modified packet stream that contains the secret message. Note that you will not need all the packets that you are given
