Sensors and Transducers and IntroductionBasic Electronics ... There are many different types of sensors and transducers available in the marketplace, and the choice of which one to use really depends upon the quantity being measured or controlled, with the more common types given in the table below: mon Sensors and Transducers Electronic oscillator A low frequency oscillator (LFO) is an electronic oscillator that generates a frequency below approximately 20 Hz. This term is typically used in the field of audio synthesizers, to distinguish it from an audio frequency oscillator. An audio oscillator produces frequencies in the audio range, about 16 Hz to 20 kHz. High Pass Filter Passive RC Filter TutorialBasic ... The above circuit uses two first order filters connected or cascaded together to form a second order or two pole high pass network. Then a first order filter stage can be converted into a second order type by simply using an additional RC network, the same as for the 2 nd order low pass filter.The resulting second order high pass filter circuit will have a slope of 40dB decade (12dB octave). Frequency Generators Projects and Circuits Here is a 1Hz pulse frequency generator using the popular timer IC 555 which is wired as an Astable 1 Hz Generator and 2 Hertz Oscillator Circuit P.
