### Transformer provides no attenuation for differential transients

I have read few articles about transformers and they all point to the fact that they are excellent attenuators for common mode transients, but not for differential mode transients! One of this ...

### How can I make a simple voltage-controlled attenuator?

Having discovered just how awful the AC ripple is on some of my 5VDC wall-adaptors, I decided to make an Arduino program to calculate the RMS AC component and DC component of an adaptor under varying ...

### are amplifier and attentuator bascially of the similiar function?

I just got a very old function generator (I can't even tell the manufacture and the model number) to produce sine wave. I open it and see a big module label video amplifier. The function generator ...

### finding insertion loss for a t-pad attenuator

Lets say we have a T-pad attenuator whose series arm is 100 ohms and shunt arm is 1750 ohms. What if we terminate the attenuator network with a 300 ohm impedance. How do we find the insertion loss?(as ...

### how to derive resistance vaules (attenuator)?

Let's say we have this types of attenuator pads: How do we derive their resistance values? like shown below Where did Zo, k come from? How about R5, R3 and R7? edit: Zo represents the ...

### Measured VS Ltspice Difference in P-Chan JFET Attenuator

The following circuit is a slow switching +-15V audio signal attenuator: Why are the measured voltages (shown in white boxes) so different from the SPICE values (shown in the graph)? Note that ...

### Voltage Controlled Attenuator

I'm trying to create a DC voltage attenuator which linearly scales the loss relative to an applied control voltage "Vc". In other words, K = Vout/Vin is a linear function of Vc. Vin is guaranteed to ...

### Attenuator for guitar amp cheap DIY

I have a Peavey LTD 400 steel guitar amp. I want to overdrive the tubes in it, but it is a very loud amp. To practice I would like an attenuator between the amp and the speaker. I've seen a lot of DIY ...
