Abstract: PURPOSE:To enable a pellet bonding without requiring oxcillating operation by compressing a semiconductor pellet on a melted solder dropped on a lead conductor in such a manner as to cause vibration after oxides are removed in a high temperature reducing atmosphere from the conductor. CONSTITUTION:A lead conductor 1 is passed through a high temperature reducing atmosphere to remove oxides from the surface thereof. A melted solder 5 is dropped on the lead conductor 1 and a semiconductor pellet 3 is compressed on the solder still virating due to the energy given by dropping. Then, the pellet is connected to other leads with a wire 4. This prevents the oxidation of the solder while eliminating the need for oxcillating operation by utilizing the vibration of the solder thereby providing an inexpensive, high quality semiconductor device.

Furthermore, the offset elimination filter 68 is operated so as to eliminate the offset component of the input signal. Therefore, the predicted value of the adaptive prediction filter becomes the one with superior predictive capacity, and also, no deterioration in a quantizing characteristic for a modem signal occurs. Also, it results the variation of a bit rate, and it is possible to respond to application on a DSI sufficiently. In such a way, it is possible to realize the fast transmission of the modem signal, and to respond to a method to solve the shutout of a call used in a DSI system generally.
