Analog and Digital Recording essays

Analog and Digital Recording essays When you listen to a tape, do you know how the sound got there? When you purchase a CD or a record, do you know which will sound better and last longer? Do you know the components of Digital and Analog recording? In this essay I will define, explain and compare the similarities of Digital and Analog recording. Analog recording means, the wave form of the recorded signal resembles the wave form of the original. (Alten) Records were of the few amongst the beginning of Analog recording, however compared to Digital recording, Analog has a low frequency control due to the fact that the amplitude of the electrical signal produced was proportional to the side to side velocity of the stylus. (Walsh) Something in which people listen to frequently is Audiotape. Audiotape in Analog recording is defined as the conversion of electrical signals into magnetic signals in the recording stage and then it is encoded onto tape. When the tape is played back, magnetic signals are then reconverted back into electrical signals. (Alten) The composure of Audiotape recording is a stripe of plastic which has been coated with material that is easily magnetized. It has three heads, which are the Erasehead, Recordhead and the Playhead, which is also known as the E.R.P. (Alten) The signals that are applied to the Recordheads are equalized according to the speed and the tape type. (Digital Domain) The functions of the three different types of Heads are as follows. The Erasehead; neutralizes the polarities of the magnetic particles to remove sound from the tape. (Alten) This is why most people are careful of hitting that record button by accident, while playing valuable information. The Recordhead is the one we use when dubbing a song or our voices to tape. It carries two signals, the record bias current and the audio current. This signal ...
