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.

### Terms

- Signal: Electrical information passed between devices, rather than necessarily the main power supply.
- Rating: A value stating the conditions for which equipment is specified.
- Schematic: A drawing showing function and connections rather than physical appearance.

## What it represents

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 qualifier in the digital context.

## How to read it

- State scale factor and quadrant capability.
- 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.

## Important distinction

A summing element adds signals; the multiplier forms their product.
