The ........... mode provides synchronization for the entire stream of bits must. In other words, it guarantees that the data arrive at a fixed rate.

A .......... digital signal includes timing infor the data being m transmitted.

In decoding a digital signal, the receiver calculates a running average of the received signal power, called the ............

The most common technique to change an analog signal to digital data is called ..........

The first step in PCM is .........

There are three sampling methods

.......... finds the value of the signal amplitude for each sample; ........... finds the change from the previous sample.

While there is (are) only ............ way(s) to send parallel data, there is (are) ........... subclass(es) of serial transmission.

In .......... transmission, we send 1 start bit (0) at the beginning and 1 or more stop bits (1s) at the end of each byte.

In ............. transmission, we send bits one after another without start or stop bits or gaps. It is the responsibility of the receiver to group the bits.
