    <div class="sphx-glr-thumbcontainer" tooltip="A power amplifier compresses the large amplitudes: its AM/AM (and AM/PM) conversion is linear at low power and saturates. Driven by OFDM, whose peaks are rare but high, it creates in-band distortion (EVM) and out-of-band emission (spectral regrowth, measured by the adjacent channel leakage ratio, ACLR).">

    <div class="sphx-glr-thumbcontainer" tooltip="A converter of N bits and full scale A rounds every in-phase and quadrature sample to one of 2^N levels spaced by \Delta = 2A/2^N, and clips beyond \pm A. comnum.adc and comnum.dac model it, with an analogue bandwidth, the noise of an effective number of bits (ENOB), the sampling-clock jitter (ADC) and the zero-order hold (DAC); the adc and dac blocks put them in a link.">
