detector circuit การใช้

• The detector circuit maintains a constant current between the two detector electrodes during titration.
• Plate detector circuits usually lack an A . V . C . bias circuit.
• A photoresistor can be applied in light-sensitive detector circuits, and light-and dark-activated switching circuits.
• This made plate detector circuits more practical for low-priced radios sold during the depths of the Great Depression.
• An early form of envelope detector was the infinite-impedance detectors ( peak detector circuits ), and precision rectifiers.
• Like a telephone, an answering machine has a detector circuit that waits for a ring signal from the phone company.
• Diode detectors were popular because, unlike plate detector circuits, they could also provide A . V . C . bias.
• Individual op-amps can be screened for popcorn noise with peak detector circuits, to minimize the amount of noise in a specific application.
• :: : OK If its modulated, you can make a circuit to respond only to the modulation ( a detector circuit ).
• The detector circuits were able to send impulses to guide the car and determine the presence and velocity of any metallic vehicle on its surface.
• For example, an overcurrent protective relay may have a AC to DC power supply for the input circuit, a level detector circuit and an RC time delay circuit.
• The grid leak detector circuit output, often taken from the plate of the detector tube, may require additional filtering to remove remnants of the carrier portion of the received signal.
• A "'window detector circuit "', also called "'window comparator circuit "'or "'dual edge limit detector circuits "'is used to determine whether an unknown input is between two precise reference threshold voltages.
• A "'window detector circuit "', also called "'window comparator circuit "'or "'dual edge limit detector circuits "'is used to determine whether an unknown input is between two precise reference threshold voltages.
• In other cases, the long term DC value of the modulated signal is important, as building up a DC offset will tend to bias detector circuits out of their operating range.
• Product detector circuits are analog multipliers and so essentially ring modulators or ring of diodes or a single dual-gate Field Effect Transistor to anything as sophisticated as an Integrated Circuit containing a Gilbert cell.
• Plate detectors have the advantage in that they isolate the detector load from the input circuit more effectively and may be employed where sensitivity is thought to be otherwise compromised by a grid leak or diode detector circuit.
• Perhaps the most critical memo was one written by Hamilton-Sundstrand engineer Donald Bateman, who wrote : " Based on recent flight demonstrations . . . of the MK II GPWS, I have become very concerned about the Excessive Rate Detector Circuits in the MK II computers.
• Instead of activating a bell, the detector circuit waits a certain number of rings and then automatically closes a circuit between the answering machine and the phone company, signaling an " off-hook " condition, which is the phone company's cue to open a voice connection with the caller.
• This form of " electronic warfare " cuts both ways-since detector-detectors use a similar superheterodyne receiver, many early " stealth " radar detectors were equipped with a radar-detector-detector-detector circuit, which shuts down the main radar receiver when the detector-detector's signal is sensed, thus preventing detection by such equipment.
