Signal Recording

Lecturer:

Tutor:

Supervisor:

Department of Radioelectronics

Synopsis:

The subject deals with ways of analogue and digital recording of sound and video signals on tapes, discs and into solid state memories. Acquired knowledge can be used in servicing sound and image recording devices, in radio and television studios and in recording studios. The follow up to this subject is Discrete Acoustic Signal Processing.
