<p><P>PROBLEM TO BE SOLVED: To realize a narrowband time code receiver suitable for integration without using a special crystal filter. <P>SOLUTION: This narrowband time code receiver is realized without using a special filter such as the crystal filter by switching and demodulating an output of a high frequency amplifier by switching signals whose phases cross orthogonally and then performing a prescribed arithmetic operation. <P>COPYRIGHT: (C)2004,JPO</p> |
