http://www.rfresponse.com/calculators/ip3_3tone_ofdm.php WebThe cross-modulation correction circuit provides up to 20% cross-modulation distortion correction in 4 steps of 5% each. The circuit is designed for use primarily in making direct positive sound tracks, although it may be used in some circumstances in making conventional negative sound tracks.

WebCROSS MODULATION DISTORTION: This is another form of multi-tone distortion. The non-linear device causes modulation on one signal of frequency f 1to be transferred to a second signal or carrier of frequency f 2. The intercept point for this distortion product is generally 2.5 dB below that for the third order harmonics [3]. 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 induces an effective reduction in gain, partially amplitude-modulating the second signal. If SID only occurs for a portion of the signal, it is called "transient" intermodulation distortion. mcnary band calendar
Swept IMD and IM Spectrum Concepts
WebThe total difference for the aggregate distortion from cross modulation products vs intermodulation products are 6 dB + 10·log10 [27720·6 / 1540·2] = 23.3 dB, assuming the … WebCross-Modulation Distortion Testing. The cross-modulation test serves recording engineers very much as the light meter serves photographers. That is, it helps them determine the proper light exposure to be used when producing a photographic image. The photographer judges the quality of the photograph by viewing it. WebCross modulation distortion is expressed as the ratio of the target channel carrier level to the level of modulated components of the carrier of the target channel resulting from modulated signals of undesired channels. Swept IMD supports an XMOD parameter which is calculated as follows: XMOD=-2 (Pi-Ps)+6dB+20Log (N) Where: mcnary bergeron \\u0026 associates
