: Determines the analyzer's ability to distinguish between two closely spaced signals.

: In digital analyzers, the signal is sampled in the time domain, and a computer or microprocessor performs an FFT algorithm to calculate the frequency components. This method is highly attractive for its precision and speed, though it was historically more rare. Key Components & Parameters

: This architecture uses a series of parallel filters, each tuned to a different frequency. While this provides a real-time view of multiple frequencies simultaneously, it is often more complex and expensive to implement for broad spans.
