A process for production of a functional film comprises a coating liquid preparation step of preparing a coating liquid; an application step of applying a monolayer of the prepared coating liquid onto a substrate ; and a drying step of drying the applied coated layer. For this purpose, a signal replica of the signal from the nearby base station is generated and the replica is subtracted from a receiving signal. The controller for adaptive programming and calibration of the receiver, transmitter and LO generator. The flange of the hood inner panel is connected to the level difference portion of the hood outer panel using an adhesive agent. When present, the pre-emphasis, pull-down and pull-up cells are connected in parallel across the external load to provide pre-emphasis features to the output.
