This abstract describes the observation of a roll-off rate of 12dB per frequency octave for the microwave power gain of a modulation-doped field effect transistor (MODFET) at 90 K, and a roll-off r

The frequency response of an FET amplifier within a high-speed GaAs integrated circuit has been measured directly using ultrashort optical pulses from a gain-switched InGaAsP injection laser and th

Frequency sampling filters are filters whose frequency responses are synthesized as the sum of elemental frequency responses of the form (Fig.

Frequency scaling of speech signals is a useful method for reducing the bandwidth requirements in analog and digital speech transmission systems.1"5 In analog systems the frequency compressed signa

D URING World War II, single-channel and multichannel frequencyshift radio telegraph systems proved of the utmost importance in providing the Allied Powers with a world-wide automatic printing tele

Frequency dependent cyclotron resonance measurements are reported on Ga(.47)In(.53)As-InP and Ga(.47)In(.53)As-Al(.48) In(.52)As heterostructures.

The variational equations that describe the propagation and interaction of two pulses of different frequency are derived from the nonlinear Schroedinger equation and used to obtain analytical formu

A possible experimental determination of the elements of the permeability tensor of a magnetized ferrite at any frequency and magnetic field rests 011 the measurement of the frequency shift that th

Frequency stabilization of FDM optical signals to a comb of equally-spaced frequencies has been demonstrated for optical signals originating from different locations.

We report a heterodyne beat with a line width of 5.6 ± 0.6 Hz between two cavity-stabilized quantum cascade lasers operating at 8.5 micron.
