IEC analogue multiplier element
Analogue element with a multiplication mark whose output is proportional to the product of two inputs.
In plain English
What does IEC analogue multiplier element mean?
An analogue multiplier element produces an output proportional to the product of its inputs, usually scaled by a fixed factor such as one tenth of a volt per volt squared. IEC-style diagrams draw it as a rectangle with a multiplication mark; TI's logic overview uses the Greek capital pi as the multiplier additional drawing mark in the digital context.
A simple example
Multipliers appear in power calculation from voltage and current signals, modulators and gain-control circuits. The scale factor and the quadrant capability must be stated, because a one-quadrant device cannot handle negative inputs.
What the drawings help you do
The element does not show accuracy or bandwidth. Those govern whether a hardware multiplier or a digital calculation is appropriate.
This particular reference
Analogue element with a multiplication mark whose output is proportional to the product of two inputs. A summing element adds signals; the multiplier forms their product.

- Identify which inputs carry voltage and current in power calculations.
Information to show or reference
- Mark the multiplication function.
- State the scale factor.
- State quadrant capability.
A distinction that matters
A summing element adds signals; the multiplier forms their product.
