Signal Amplification
Signal amplification is the process of increasing the strength of a signal, making it easier to detect and analyze. This is commonly used in various fields, such as telecommunications and electronics, where weak signals need to be boosted for clearer communication. Amplifiers, which are electronic devices, play a crucial role in this process by taking a small input signal and producing a larger output signal.
In biological contexts, signal amplification can refer to the way cells respond to external stimuli. For example, when a hormone binds to a receptor on a cell's surface, it can trigger a cascade of reactions that amplify the initial signal, leading to a significant cellular response. This mechanism is essential for processes like metabolism and immune response.
