Signal frequency ratio

WebSpectral Measurements. Channel power, bandwidth, mean frequency, median frequency, harmonic distortion. Use obw and powerbw to find the 90% occupied and 3-dB bandwidths of a signal. Compute the mean or median frequency of a power spectrum. Estimate the power over a given frequency band. Radio frequency (RF) is the oscillation rate of an alternating electric current or voltage or of a magnetic, electric or electromagnetic field or mechanical system in the frequency range from around 20 kHz to around 300 GHz. This is roughly between the upper limit of audio frequencies and the lower limit of infrared frequencies; these are the frequencies at which energy from an oscillating current can radiate off a conductor into space as radio waves. Different sources speci…
