Peak to Peak Detector - Working Principle and Applications: A half-wave rectifier with a capacitor-input filter provides a dc output voltage roughly equal to the peak of the input signal.…
Zero Crossing Detector Circuit: Zero Crossing Detector Circuit basically involves the sine to square wave conversion by a level detector circuit followed by a pulse circuit, which consists of one…
Voltage Level Detectors: Voltage Level Detectors - Operational amplifiers are often used in circuits in which the output is switched between the positive and negative saturation voltages, +Vo(sat) and -+Vo(sat). The…
Waveguide Mixers and Detectors: As we know that ordinary transistor and tube RF amplifiers eventually fail at microwave frequencies, because of greatly increased noise, compared with their low-frequency performance. Unless…
Ratio Detector Circuit: In the Foster-Seeley discriminator, changes in the magnitude of the input signal will give rise to amplitude changes in the resulting output voltage. This makes prior limiting…
Slope Detector FM Demodulation: Consider a frequency-modulated signal fed to a tuned circuit whose resonant frequency is to one side of the center frequency of the FM signal. The output…
Simple Diode Detector: Operation of diode detector: The Simple Diode Detector is by far the most common device used for AM demodulation (or detection), and its operation will now be…
Speed Detector: One important factor in the closed loop control of variable speed drives emÂploying solid state converters is the Speed Detector. In the dedicated hardware control using analog components,…
