A signal processing circuit has two types of filters: an IIR filterand an FIR filterhaving an equivalent transfer function at all times. In an adjustment mode in which the signal processing circuit is adjusted to have an arbitrary transfer function, the signal processing circuit makes a configuration setting to use the IIR filter. When completing the adjustment or in a signal processing mode, the signal processing circuit makes a configuration setting change to switch to the FIR filterhaving the equivalent transfer function.

A signal receiving apparatushas a memory circuit, writing of data contained in a digital input signal transmitted from a signal transmitting apparatusis performed using a clock signal separated and created by a PLL circuitfrom the digital input signal received, and reading is performed using a reference clock signal with quartz accuracy from a reference clock generating circuit. To reproduce the digital input signal by correcting the shift between the clock signal and the reference clock signal, the signal receiving apparatus detects the shift between the two clock signals. When the signal receiving apparatusside lags behind the signal transmitting apparatus, the data contained in the digital input signal undergoes thinning out, and when it leads, a signal generated from previous and subsequent digital input signal is interpolated.

A method of separating and recovering F from O water at high purity and efficiency while maintaining the purity of the O water. By using a solid electrode ( ) as an anode and a container (electrodeposition vessel) ( ) made of platinum as a cathode, F in a solution ( ) is electrodeposited on the solid electrode surface by applying a voltage. Then, by using the solid electrode ( ) on which F is electrodeposited as a cathode and a container (recovery vessel) ( ) holding pure water therein as an anode, F is recovered in the pure water by applying a voltage of opposite polarity to that of the electrodeposition. In this process, little O water is lost. The initial concentration of the O water is maintained even after the electrodeposition of F, so that the O water can be repeatedly used as an irradiation target for production of F.
