sharing signal and power ground - Circuit design | Eng-Tips I generally share the signal and power ground together for analog(and mixed circuits <1 KHz) Does this practice introduce noise in the system The circuits many times does not work if I separate them, so I am forced to do it to make it work Am I missing something about designing here
Faraday Cage Shielding by Frequency 4 - Eng-Tips That said, it is very plausible that the submarines picked up only the H-field with their antennae, which had to be quite small in comparison to the 17,2 kHz (wavelength around 17 km) used by at least one of these stations See
Eng-Tips is the largest engineering community on the Internet I have available an old HP Spectrum Analyzer Tuning frequency, Bandwidth, Scan Width and Input Attenuation controls are available on the HP 8554L RF section The IF HP 8552B section provides bandwidth gain selection and detection I would like to determine the SSB Phase Noise of a signal
Mechanical Acoustics Vibration engineering - Eng-Tips Dear bohica,The mV g is a unit for sensitivity factor relating the voltage output of an accelerometer to the acceleration unit g = 32 3 ft sec*2 = 386 4 in sec*2 = 9 81 m s*2 The mm s is a unit of velocity (one parameter of vibration parameters, i e , acceleration, velocity and displacement)Now to convert the acceleration output to velocity reading, you need to know your accelerometer
Grounded vs ungrounded capacitor banks 1 - Eng-Tips As far as Cannons' Technology, it is simply a case of their 12 5 Khz signal being shunted to ground due to the low impedance of the caps at that frequency (which is the reason for the blocking units)
Can I get meaningful data from dried seafloor samples 2 - Eng-Tips I think that I can get proper core samples of about 60 to 90 cm length at low cost to our project Longer cores will be costly to get In the next few days, we will be doing some 3 5 KHz sonar work, which should give a pretty good indication of the deeper sediments and stratifications to see if the deeper soils are similar to those at the surface
full-bridge PFC - Circuit design | Eng-Tips Hello, I am designing a full-bridge active power factor corrector for a 600W SMPS The circuit diagram is as follows:- I cannot use a standard boost converter type of PFC as the power level is too great MOSFETs 1 4 come on together …and 2 3 are the other pair which come on together
