all possible noise due to breadboard

[snishanth512]

what are possible noises due to breadboard?

How to remove those noises?

I just connected the breadboard to the DSO(Digital Oscillator).

I found a lot of noise.

Why is that so?

Wires and inner tracks acts as Antennas.
It is hard to improve noise immunity.

Does it acts as a capacitor ? (I mean holes present in the breadboard)

As far as this noise is concerned there is no need to worry much if we don't go for higher frequency operation. Also for the question you asked i don't think that whether it acts as capacitor is really a concern for the verification of the normal circuits. May be it is a capacitor but there is no need to worry unless we are going to use a very sensitive design.

The holes you see are built in plastic matherial, which doesn´t have significative effect shielding noise fields.
You must se breadboard as a set of the inner long tracks, which really acts as antennas.

If assembled circuit is mainly digital operating under low frequencies, don´t worry about that.
However, if analog devices are included, the noise effect will affect signals.
