From the following statements, select all that correctly describe the digital transmission of analog data.

Group of answer choices

One method used to reduce the difference between the digitized analog signal and the original analog signal is to increase the number of samples taken of the analog signal.

When it is necessary to digitally store or transmit an analog signal, a special device or computer program known as a codec is used to translate the analog signal into a digital signal.

An analog signal that has been digitized is only a rough approximation of the original analog signal, and the difference between the two signals is referred to as quality error.

When translating an analog signal into a digital signal, the number of bits used per sample must increase whenever the number of samples taken per second increases.

It is necessary to use a modem to transmit analog data over a digital circuit.
