Hi, I'm not sure but I think you haven't connected the three terminals or the switch - one to pull-up resistor, one to GND and one to the control signal. It looks like terminal 1 is not connected.
Hi All, I have a small array of four panels on my roof each 1640x992x40mm, they are supported by two horizontal rails each secured to the roof timbers with three heavy duty brackets and long screws. My problem is in winter when the sun is low a telephone cable that flies across my property causes a shadow just visible in
HEllo everyone Currently I am working on a boost converter thesis project and my task is to find losses in the inductor. Its hardware based work. I have three questions regarding inductor losses 1- For the given coil, core material properties are not given in the data sheets and I also contaced coil supplier but no response from them perhaps
I trued a series modulator to see how easy or not could it be. Here is the circuit so far, but the LPF will change to a 160m LPF when I finish with the rest of the TX. I removed the final stage and kept just three bjts to experiment at lower power first. Without any audio and without any LPF, I measure 1.7W (square wave) when the output is loaded
For the Main Power Amplifier, you've got three options. Max. Delivered Power OR Max. Efficiency OR Max. Gain. Nor of them is overlaps in practice so you have to choose one of them which is more beneficial for your requirements.The others will automatically aligned according to the principal one.
Hi all, If i have three modules, one is top and other two is instaintiated in that top module. In top i have declare an inout port a and in other two modules i declared the same port as input a and output a. So is it correct way of declaration?
The three possibilities are: 1) Conducted EMI (power supply and ground noise) 2) Radiated EMI (pickup on long high impedance wires) 3) Spurious signaling (control wires being bounced at the source) 1) and 3) can be traced methodically with an oscilloscope. 2) is tougher, just attaching a probe to a suspect node may alter its Z0 to the point t
Hi, The data sheet of an antenna system can be found at This description is taken from it: Our XY pedestal is ideal for tracking satellites in Low-Earth Orbits (LEOS) because it completely eliminates the problem of the overhead keyhole more reliably a
There's a lot more to it than just u0CoxW/L (and three, at least, moving at once for different influences). Advanced technologies add all sorts of features to get an "acceptable" reliability - LDD and halo details in the source region can degrade gm a lot (you'll see RF folks fight for their own, "not digital", transistor since they don't care a
The three blue wires go to the motor (if the motor runs in reverse, you need to reverse any two). The red-black pair goes to the power supply. The connector goes to the board.
I am having trouble in defining in a unit cell of loaded three legs frequency selective surface in CST. Can anybody give me a hint. thnk guys
The mean of "measure return loss between two pads on my pcb" seems not very clear to me. I would guess you want to measure the returnloss at two points on your PCB? Yes, you need to solder an extension cable to your measurement point as access point for VNA. If you just want to obtain the magnitude of the returnloss, you don't need to do extra c
Anyone familiar with these oscilloscopes? These scopes have functions to measure quantities like RMS value of voltage. When you do that, you get several output values. These are named: "Value", "Mean", "Min", "Max" and "StDev". (I mean, you get these five output values for each measurement you do. In the case of RMS measurement, for example,
First: Do not wait for someone to do it for you. Second: Divide the problem into smaller parts, and solve them step by step. three: Ask for help when you find difficulty in any particular subject, not general.
Voltages are relative, as long as the triac has sufficient gate to A1 voltage it will fire, no matter what the absolute voltages above ground are. Yes, as long as the output voltages at P1, P2 and P3 are high enough it should work but beware that those output voltages are relative to VSS and the three triacs may not share a common connection with
You would start with a reasonable equivalent circuit of an opto isolator. The shown three pin device obviously isn't.
I think you need to first decide: is this 8 registers, or is it something else. That will determine what your approach should be. If I understand correctly, you have three interfaces: "external", A and B. A A dual-port RAM will help, but having three interfaces definitely complicates this.
It's actually more of a voltage stabilizer. Drawn in more conventional way, it is an emitter follower with the base voltage held constant by the Zener. All R1 and the three diodes do is limit the output current. It isn't constant current, it's constant voltage with current limiting, almost the opposite of constant current. Under light loa
Hi, It makes the shareholders nervous that the new models won't be ready in three months and they start hoping to get rid of Elon, I think.
Hi, IMHO, It doesn't matter if it's obsolete, it matters if it's available and fulfils the required function. ...And isn't overly expensive. I guess you want PDIP... Jaycar sell the XR2206, it's only $20... What about the XR2209 (8-pin version)? I recollect RS UK were selling them off at ~$6 each three years ago. Failing that, op amps can ma
