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

Question

Suppose an analog audio signal comes an over a wire, and the voltage on the ware 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 bits, such that 0 V wouId 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: 0V 0V V1 2V 3V 2V 1V. Show the signal converted to digital as a stream of 0s and 1s. Convert the following binary numbers to decimal numbers a) 100

Explanation / Answer

The encoded system has,

0 V=00

1 V=01

2 V=10

3 V=11

The digital signal has the voltages 0V 0V 1V 2V 3V 2V 1V.

Therefore, the digital signal as a stream of 0s and 1s is 00 00 01 10 11 10 01.
