A digital input (in the form of a number) is converted into analog format, which could be a voltage or a signal frequency, for example. An example, which most people would be familiar with, is your touch tone phone. When you press a key on the phone, that is a digital input. The output is actually 2 frequencies mixed together (analog signal). Each row of keys on your phone is associated with a frequency, and then each column of keys is associated with a frequency. The two frequencies combined represent the row and column of the key that was pressed. At the phone company, they use analog filters to determine what frequencies were generated by your phone, and from that, determine which key was pressed (this is Analog to Digital conversion).

What are the types of ladder network?
If you are referring to Ladder network in digital circuit or digital to analog conversion the ladder means cascading of component which are R-2R ladder circuit from conversion of analog to digital. it is used for obtaining the low value of resistance.
What are AD and DA?
AD is Analog to Digital conversion the use is to do digital measurements of analog voltages and currents, a computer soundcard is an AD converter that convert analog sound to digital sound so that it can be played on a computer, and DA is the opposite, digital to analog conversion, the digital sound on the computer is converted to analog sound to drive a speaker or headphone
Is PCM is an example of analog to digital?
No, Pulse Code Modulation is a communication method used to carry digital data but is not part of any analog to digital conversion. PCM is often used to carry audio data as a digital stream and therefore is the encoding used as the signal is first converted to a digital format.
