An LM555 timer paired with an NTC thermistor makes a simple, configurable ON/OFF thermostat for heating or cooling.
Abstract: The time delay in the control link will affect the small signal stability of the line commutated converter based high voltage direct current (LCC-HVDC) system. This article establishes the ...
This paper presents a novel design of an X-band (812 GHz) 4-bit monolithic microwave integrated circuit (MMIC) type true-time-delay (TTD) line for wideband high-resolution imaging radar applications.
Abstract: This work presents a programmable, linear, periodically time-variant (LPTV) bandpass true-time-delay line which does not require a dedicated tunable clock-phase delay generator. The ...
