A discrimination circuit is an electronic circuit that is designed to differentiate between different input signals or conditions and produce a specific output based on those differences. These circuits are commonly used in various applications such as signal processing, communication systems, and control systems to selectively process or respond to specific input signals while ignoring others.

Discrimination Circuit
A discrimination circuit is an electrical circuit designed to distinguish between input signals based on specific characteristics, particularly in the context of pulse or digital signals. It compares the input signal to a reference value or pattern and produces an output that indicates whether the input matches the reference.
Function:
- Determines if an input signal meets predefined criteria, either in terms of:
- Signal amplitude (level discrimination)
- Pulse width (pulse-width discrimination)
- Time interval between pulses (pulse-interval discrimination)
- Presence of a specific pattern or code (code discrimination)
Applications:
Discrimination circuits are widely used in electronic systems, including:
- Digital Communication: Detecting and processing pulses in data transmission and reception
- Control Systems: Monitoring and responding to specific sensor signals
- Timing Circuits: Generating precise time intervals
- Security Systems: Verifying access codes
- Medical Electronics: Distinguishing between different types of medical signals
Types:
There are various types of discrimination circuits based on the characteristic being discriminated:
- Level Discrimination: Compares signal amplitude to a threshold voltage
- Pulse-Width Discrimination: Measures the duration of a pulse and compares it to a reference value
- Pulse-Interval Discrimination: Detects the time interval between consecutive pulses
- Code Discrimination: Identifies specific patterns or codes in a digital signal
Components:
Common components used in discrimination circuits include:
- Comparators
- Logic gates
- Flip-flops
- Timers
Operation:
The operation of a discrimination circuit typically involves:
1. Comparing the input signal to the reference value.
2. Generating an output that indicates a match or mismatch.
3. The output can be used to trigger events, set flags, or provide control signals.
