Suppose an analog audio signal comes in over a wire, and the voltage on the wire

Question

Suppose an analog audio signal comes in over a wire, and the voltage on the wire can range from 0 Volts (V) to 3 V. You want to convert the analog signal to a digital signal. You decide to encode each sample using two bits, such that 0 V would be encoded as 00, 1 V as 01, 2 V as 10, and 3 V as 11. You sample the signal every 1 millisecond and detect the following sequence of voltages: 3V 1V 3V 2V 0V 0V 1V. Show the signal converted to digital as a stream of 0s and 1s. Note: Give your answer as a continious sequence of 0s and 1s without spaces in between.

Explanation / Answer

Since we are recieving the following sequence of voltages: 3V 1V 3V 2V 0V 0V 1V

the digital stream of this would be: 3V(11) 1V(01) 3V(11) 2V(10) 0V(00) 0V(00) 1V(01)

Stream would be = 11011110000001
