Abstract
A variable delay line detector ( )includes a power splitter ( ), a mixer ( ) and a variable delay line ( ). Various devices are suitable for the variable delay line ( ), such as a non-linear transmission line (NLTL). By providing a variable delay line, the variable delay line detector ( ) is adapted to be programmed in real time thus making it suitable in applications where the phase and or frequency of the input signal varies. As such, the variable delay line detector ( ) may be used in applications heretofore unknown, such &a an inexpensive demodulator in a frequency hopped spread spectrum system.
