A PCM encoder for balloon sondes
Abstract
The encoder mainly consists of two plates: PCM master and PCM data. A low scanning frequency was chosen. The PCM data transmitted from the sonde are recorded on tape at low speed and can be played back at higher speed. System flexibility is emphasized. The system is universally programmable.
