摘要: A communication system includes a modulator configured to generate a modulated signal responsive to at least a data signal, and a demodulator configured to demodulate the modulated signal responsive to a first carrier signal. The demodulator includes a filter configured to generate a filtered first signal based on a first signal, and a gain adjusting circuit coupled to the filter. The first signal is based on the first carrier signal and modulated signal. The filter has a gain controlled by a set of control signals. The gain adjusting circuit is configured to adjust the gain of the filter, and to generate the set of control signals based on a voltage of the filtered first signal and a voltage of the first signal. The gain adjusting circuit includes a first peak detector coupled to the filter, and configured to detect a peak value of the voltage of the filtered first signal.

摘要: An LED lamp includes: a lamp shell; a passive heat dissipating element having a heat sink, and the heat sink including fins and a base and connecting to the lamp shell; a power source disposed in the lamp shell; and a light board connecting to the heat sink and including LED chips electrically connected to the power source. A chamber of the lamp shell is formed with a first heat dissipating channel. The first heat dissipating channel has a first air inlet at an end of the lamp shell. Another end of the lamp shell has a heat dissipating hole. A second heat dissipating channel is formed in the fins and base. The second heat dissipating channel has a second air inlet. Air flows into the second air inlet, passes through the second heat dissipating channel and flow out from spaces between every adjacent two of the fins.

摘要: A quantum computer hardware apparatus may include a first stage, which is connected to one or more signal generators, and a second stage adapted to be cooled down at a lower temperature than the first stage. Superconducting qubits are arranged in the second stage. The signal generators are configured, each, to generate radio frequency (RF) signals to drive the qubits, in operation. The apparatus may further include an intermediate stage between the first stage and the second stage, wherein the intermediate stage comprises one or more coolable filters, the latter configured for thermalizing RF signals from the signal generators. Related methods for thermalizing radio frequency signals in a quantum computer hardware apparatus are also disclosed.

摘要: A circuit comprising: a passive reactive component; and an active circuit, the active circuit arranged to increase the ac voltage difference across the reactive component by changing the current at an input to the reactive component and the current at an output of the reactive component by equal and opposite amounts. By increasing the current on one side of the resonant circuit and decreasing the current on the other side of the resonant circuit, the amount of current flowing through the resonant circuit is increased and thus the ac voltage difference across the inductor of the LC resonant circuit is increased. The Q of an inductor (the ratio of its imaginary to real impedance) is increased. In a filter, the improved Q provides a sharp, high rejection notch and faster pass-band to stop-band roll-off, thus improving the frequency response of the circuit.
