Abstract

We develop a mathematical description of the response of systems to second-order memory mechanisms based on a time-varying gain modulation function. We show that intermodulation products arising from interactions at baseband have different phase symmetries from both interactions at second-harmonic frequencies and gain compression and thus, may be readily distinguished through measurement. We also use a technique for measuring and aligning the phase of intermodulation products outside the measurement bandwidth of our instrumentation to identify contributions to memory with broad frequency response.
