hello have you got a galvanic insulation for your AC signal ? Any link with the MAin AC power ( ground, earth,neutral) Maybe your AOP can oscille at H.F., because high speep AOP. you can reduce the Frequency band width C accross feeback
Consider what happens in case of a near by lightning strike, and I'm sure you'll want to keep the signal ground separated from cable shield and earth.
can i connect directely signal grund(5v smps 0v) to earth ground are i can use a resistor are capacitor if so kindly tel the value of the passive component. regards kalyan
hello, Even working in differential mode, signal is referenced from the 0V, so before, test if you have ground probleme between both equipement ... or earth connections ? any difference of potentiel (Volts AC or DC) beetwen ? if not, you can connect both 0V (5V) and 0V(Servo ground) If (...)
There are different situations where "buzz" or hum can be expected: - ground loops that are created between two devices involved in an audio transmission which have both protective earth connection, e.g. a PC (always PE connected) and a TV with antenna connection - long audio cables with single ended signal connection - (...)
I have two design solution for low frequency (<1KHz) voltage signal amplifier, where instrument amp has fixed gain of x10 and x20 for low noise performance. The source impedance is quite low. I have one design than work on +/-5V PSU where AGND is common/analogue ground plane, which attached to -VE of the instrument amp. It would requires (...)
..theres no cct diagram. So do you think its ok if i snip the earth out of my three pin plug?
oscilloscopes often have ground currents floating on their chassis, so it is hard to tell if the signal you are seeing is real or not. Try looking with a different oscilloscope or a DC blocked spectrum analyzer. Try floating the chassis of the scope from earth ground. Try running your (...)
Yes, most probably it's due to noise generated in ground loops. Sheilding and earthing of board, signal cables will solve the problem. grounding metal cans of crystal. Try tv and vga signal source with removed from mains earth. This is some kind of high (...)
is it right to connect the signal ground on PCB to the earth??Should I connect the chasis ground to any one of them???? please I need urgent and accurate answers Thanks
I seriously doubt they intend for you to connect a wire between the transmitter circuit and a distant receiving circuit. Isn't the fiber optic signal supposed to be the only link? Anyway, kidding aside... There is the circuit ground icon and there's the earth ground icon. The (...)
what are the difference between signal ground,chase ground and earth ground?
ground reference : return path of power supply (can be multiple) ground earth : single and use for interference control and safety
They are all connections to the same place, a point of zero voltage but with different purposes: signal ground is a reference point from which that signal is measured, due to the inevitable voltage drops when current flows within a circuit, some 'ground' points will be slightly different to (...)
I would imagine it has to do with corrosion, if the return is truly at ground (earth) potential and the signal negative, the signal will not corrode with -48V but would be chowed quickly with +48V and any moisture at all.
I am getting three signals on ADC PIC16F873 Line, earth and Nuteral measuring them with respect to DC ground. The target of my project is to achieved Line earth and Nutral Reversal and to Measure the earth loop resistance. The signal which i am getting is Line Posative Half (...)
You may connect digital ground directly with the earth ground - I don't see anything wrong with that, after all all computers are wired that way, but I would suggest another solution: A High Current Safety Loop Breaker Circuit .. see picture below .. Regards, IanP
Hi, May I know wats the difference between the Analog ground, Digital ground, Power ground, signal ground, earth... Just how many types of ground? Thanks! Regards, Eric Mar
There are many grounds. One is the safety ground/earth of the power lines. It is connected to the earth. In circuits there is a conductor which all of the signal levels and power supply levels are referenced to. This is called circuit (...)
The ground pins on the video connector are signal return path grounds. The shell of the conncetor is grounded to the case of the computer, which is generally connected through the computer case to the grounding pin of the AC power cord (...)
