A digital pulse detector circuit having a selectable false alarm rate receives an analog input signal containing periodic correlation pulses in a background of noise. The input signal is sampled and digitized to produce a series of digital input samples which are taken for regular time slots ...
PROBLEM TO BE SOLVED: To provide the digital pulse interrupt detection circuit in which no multi-stage frequency divider is required with a small circuit scale and low power consumption. SOLUTION: An oscillation circuit 12 provides an output of a low frequency pulse at an emitter coupled logic(...
High Performance Digital Pulsewidth-Control Circuit With Programmable Duty Cycle For the pulse width control circuit, two delay lines and a time to digital detector is used which reduces the amount of hardware required in the circuit. The output duty cycle is calculated with the help of a new ...

Receiver and detection techniques which operate at a much lower sample rate than Nyquist were proposed in [2,19] and [20]. In this detector, the crossing of a preset threshold level triggers the discharging of an RC circuit with an accurately known RC-time and therefore discharge curve. Wit...
The reversible output signals of the switching circuit are added to the modulating input signal and the sum is integrated. A level detector changes the polarity of its output voltage whenever the output of the integrator reaches either of two fixed levels. The output of the level detector is ...
There follows an anxious wait by the reflow oven as mysterious clouds of smoke waft towards the smoke detector, before you remove your batch of perfect boards and wait for them to cool. Alternatively, there are other times when you want the device but you’re too impatient to wait, and ...
PURPOSE:To suppress the distortion of the output of a decoder produced while a fault occurs and when the faulty condition is eliminated, by providing a circuit abnormality detector for detecting abnormality in a transmission line in a di... E Hideaki 被引量: 0发表: 1992年 and Differential Pu...
The Sea Hunter is a true submersible metal detector with its lack of a digital display and with its knob interface. Everything is interpreted by audio, so of course, you have a headphone jack to plug in and adjustable threshold. Get your scuba gear out because you can dive to a deep ...
