Multi Slave I2C Connection guidance

[DBhut.1]

Hello,

I have one master and multiple slave devices for I2C Connections.

So, my Query is that;

I am connecting series resistors after the Pull up Resistors on SDA SCL lines,

Now the query is that should I connect those Series Resistors at only Master side or on every slave side?

for your reference I have attached Image.

What's the purpose of those series resistors?

to overcome I2C glitches, noise and any other issues.

I would avoid putting passives on the bus and find a sw workaround. Here it is the same when someone ask to RC low pass filter a PWM to get an analog value, where to place each passive component....

Each chip has around 5 pF pad capacitance.

Serial resistor will raise the ground voltage to filter noise (injected where?), or for ESD.

Etc....
