WebCalculates frequency sets that are free of intermodulation interference caused by 3rd- and 5th-order intermodulation products -- in particular two transmitter 3rd-order intermod products (2Tx 3rds), three transmitter 3rd-order intermod products (3Tx 3rds), and two transmitter 5th-order intermod products (2Tx 5ths) WebConsider the fifth order intermodulation product, or "IM5". This mix is caused by 2*F1 minus 3*F2. It's called the fifth-order because it is a combination of a second harmonic and third harmonic, and 2nd + 3rd is "5". Looking at a Practical Transmitter. An 1850 kHz LSB transmitter modulated with audio tones of 500 Hz and 3000 Hz would have main ... good diabetic protein snacks

Intermodulation (IM) or intermodulation distortion (IMD) is the amplitude modulation of signals containing two or more different frequencies, caused by nonlinearities or time variance in a system. The intermodulation between frequency components will form additional components at frequencies that … See more A linear time-invariant system cannot produce intermodulation. If the input of a linear time-invariant system is a signal of a single frequency, then the output is a signal of the same frequency; only the amplitude See more Slew-induced distortion (SID) can produce intermodulation distortion (IMD) when the first signal is slewing (changing voltage) at the limit of the amplifier's power bandwidth product. This … See more • Beat (acoustics) • Audio system measurements • Second-order intercept point (SOI) • Third-order intercept point (TOI), a metric of an amplifier or system related to intermodulation See more As explained in a previous section, intermodulation can only occur in non-linear systems. Non-linear systems are generally composed of active components, meaning that the components must be biased with an external power source which is not the … See more Intermodulation distortion in audio is usually specified as the root mean square (RMS) value of the various sum-and-difference signals … See more • Butler, Lloyd (August 1997).
