ML Detection with Symbol Estimation for Nonlinear Distortion of OFDM Signals
... power efficiency, the HPA is usually operated near the saturation region and this introduces nonlinear distortion into over all system. Unfortunately, the OFDM signal is characterized by high peak-to-average power ratio (PARR) and a large dynamic variation of signal amplitude. A highly linear power ...

2015 Using Pulse Width Modulation PWM Supply with Flux YS CN68
... After that we can compare torque and iron loss values with and without pulse width modulation to measure its impact: • Torque (figure 5) has a slightly lower mean value with PWM. This is because only the fundamental of the current generates the torque and its amplitude is less. • There are more ir ...

... The two inputs are 1 and 2. A differential voltage between them causes current flow through the differential resistance Rd. The differential voltage is multiplied by A, the gain of the op amp, to generate the output-voltage source. Any current flowing to the output terminal vo must pass through t ...

G An Examination of Recovery Time of an Integrated Limiter/LNA
... Figure 6 indicates how the limiter recovery time improves with a lower incident power level. In this plot, the power tone F2 is no longer detectable. The small-signal tone F1 is still clipping, but not as much as in Figure 4. Under these conditions, the 10–90% rise time is < 5 ns. When this testing ...

However this brings us to another fascinating aspect of human hearing, in that, while an overall 3dB change in level is not all that dramatic to the casual listener, a 3dB change to part of the signal spectrum definitely is. For example a bass or treble control that cuts or boosts signals below 300H ...

Part I - Amplitude Modulation
... 1. Verify DSB–TC: Apply a 10 kHz sinusoidal carrier with Ac = 2V (i.e. 4 Vp-p) to the X input. To the Y input, apply a message signal composed of 2 kHz sinusoid with Am = 2V and a dc offset of +4 V. Use the spectrum analyzer (linear scale is recommended) to confirm the expected frequencies and ampli ...
