Model 2026 Spectroscopy Amplifier Data Sheet
... The Model 2026 lets you select either Gaussian or Triangular pulse shaping for the Unipolar output with a convenient front panel switch. In addition, it offers a choice of six front panel switch-selectable shaping time constants for each of the pulse shaping methods. This direct control of both the ...

Pure Sinusoidal PWM Signal Generation Technique
... The Schematic diagram contains six IGBTs gates with built in freewheeling diodes which is supplied by six pulses and DC voltage source. Need of separate power supplies is due to a fact that at any instance of operation Van, Vbn, and Vcn can have any value (different from each other) so, if they have ...

Companding in Fixed Point DSPs
... • When the signals in the DSP are large, they take full advantage of the available bits. • When the signals in the DSP are small, only a few of the available bits are used. • The roundoff error is essentially independent of the signal level, so the distortion due to roundoff is much worse for small ...

However, most LDO voltage regulators oscillate with ceramic capacitor loads, as ESR value is less than the minimum required for generating the proper zero. On the other hand, the ESR compensation, as discussed ...
