This paper reports on a multi-channel FADC system which was developed for a balloon-borne experiment where flash analog-to-digital converters installed in individual channels output samples of signals at the rate of 30 MHz. The system incorporates zero suppression and data compression. The samples form the converter are put to the zero suppression on a real-time basis and then submitted to the data compression. The data compression reduces the event data in size further, so that the data of as many events as possible can be recorded onto a storage device installed on the balloon-borne apparatus. A zero suppression circuit is implemented in each channel. A data compression module in the system begins to scan all the channels, performing compression, after the converter completes sampling. The system is powered by batteries and a special care is paid to reduce power consumption of the system.
