2025年3月12日 · Delegation to DCAMM: Due to the cost of the project DCR will be doing an agency-to-agency delegation process to DCAMM through a 3-party agreement between the two agencies and the house doctor. In this case the agreement will assign the project to DCAMM in the specific amount of the project proposal.

2025年1月7日 · DCR，即动态对比度，是一种通过智能算法动态调整显示器亮度和对比度的技术。 它的工作原理是，在检测到画面中的明暗变化时，自动调整背光亮度和像素点的亮度，以此来增强画面的层次感，使亮部更亮、暗部更暗， 从而呈现出更丰富的细节。

2024年2月21日 · The Department of Conservation and Recreation (DCR) seeks House Doctors to investigate, evaluate, and prepare certifiable studies, final design services and construction administration for mechanical, electrical, plumbing and fire protection repairs, renovations, upgrades and minor replacement of various facilities within state and urban park ...

2024年2月6日 · The Key circuit modules for the Direct Conversion Receiver (DCR) and Double Side Band Transmitter are the Balanced Modulator and the Product Detector. These can take various forms such as the passive Double Balanced Mixer with the diodes and toroids or active devices like the MC1496.

If you use choices 2-4 and move on to the more complex project then you will need to have a source for the BFO frequencies such as crystal oscillators. Frequency stability in any rig is highly important -- the DCR adds another measure of complexity and that is the two sidebands -- thus you absolutely want it to stay on frequency.

一、双边带调制（DSB）相比常规调幅，调制信号 不加直流，已调信号频谱中没有载波（m (t)均值为0），因此叫做抑制载波双边带调制，简称双边带（DSB）调制。

2024年6月5日 · DCR，即动态对比度，是一种通过实时调整显示器或电视机的背光亮度来增强图像对比度的技术。 其目的是在暗场景下降低背光亮度，提高黑色表现力；在亮场景下提高背光亮度，增强亮部细节。

2021年4月22日 · 一、直流阻抗（DCR）测试目的 电池在组装成模组或PACK后,需要测试DCR值,测试的参数值主要评估焊接或连接端的阻抗值,但国外对DCR值应用更多是评估其放电功率或能量的能力。

2021年11月11日 · Our DSP gives us a scorecard every week to show us all how well we are doing. The metrics that are measured are shown as DCR, DNR DPMO, POD, CC, SC…

Our very successful 40M Direct Conversion Receiver (SPRAT #187) is being retrofitted to become a Double Sideband Transceiver on 40M, Work was done on the Code and the Display as well as the DSB...
