Abstract: PURPOSE:To change only a cut-off frequency without disturbing digital filter characteristics by interpolating gaps between coefficients read from adjacent addresses and a memory for storing the coefficients to be supplied to multipliers in the order of the addresses and supplying them to the respective multipliers. CONSTITUTION:An adjacent address calculation means 14 is provided on the input side of the address signal of the memory 12.

Abstract: PURPOSE: To accurately control the drying speed of a grain until the drying is completed by accurately correcting the humidity difference of inflow and outflow air to a value corresponding to the amount of water eliminated from the grain and accurately controlling the drying speed. CONSTITUTION: Until the water of a grain stored in a grain storage part 1 reaches finishing water, drying air heated by a burner 12 is blown to a drying part 5 and at the same time the grain is circulated to the drying part 5 from the grain storage part 1. Then, by utilizing that the difference between the soluble humidity of the inflow drying air supplied to the drying part 5 and that of outflow air corresponds to the amount of water eliminated from the grain, the combustion of the burner 12 is controlled so that a drying speed is maintained at a set speed based on the difference of the absolute humidity of the inflow and outflow air of the drying part 5. However, since water eliminated from the grain that is detected as the different between the humidity of the inflow air and that of the outflow air causes an error because of water generated in accordance with the combustion of the burner 12, the difference is automatically corrected according to the amount of fuel supply.
