What is the term for a condition of the receiver where the voltage pulse at the receiver input is excessively large?

The term that accurately describes a condition in a receiver where the voltage pulse at the input is excessively large is known as blocking. In this scenario, the excessively high input voltage can prevent the receiver from properly processing the signal, leading to a failure in signal reception. This condition often occurs when the input signal level exceeds the design limitations of the receiver’s components, notably the amplifiers, causing them to become non-functional. Blocking is significant in systems where precise signal levels are critical, ensuring that devices can operate within specified thresholds for optimal performance.

While the other terms—overloading, clipping, and distortion—also relate to signal processing, they describe different phenomena. Overloading typically refers to exceeding the capacity of a system, clipping is the result of a signal level exceeding the maximum limit of a circuit, leading to a cutoff of the signal peaks, and distortion refers to any alteration of the original signal, which can stem from various factors, including non-linearities in the circuitry.
