You have definitely encountered this situation: when taking night scenes under streetlights, some smartphones can reproduce the warm light of the streetlight, with even the texture of the leaves clearly … Read more
The new waveform of the wireless ad-hoc network based on the SDR system currently supports line-of-sight communication up to 1000 kilometers, with waveform design supporting up to 2000 kilometers. The high-power devices have increased to 40W, 80W, 100W, and 300W. The operating frequency bands support U, L, and C bands. Note: One-way delay = ping … Read more
1. Digital Gain Adjustment Method 20 * ln x = 8dB, calculating the value of x gives the multiple of the digital gain to be increased. for(int i=0;i<samples;i++){ pcm[i] = pcm[i] * powf(10.0,要调节增益大小/20.0);} 2. Dynamic Range Formula Dynamic Range = 20 * log( Maximum Value / Minimum Value) Example: The integer range represented by a … Read more
Author / Abao Editor / Abao Produced by / Abao1990 Camera Resolution Resolution is essentially linearly related to the camera’s pixel count. When assessing a camera’s resolution, the most important factor is whether it has millions of pixels. Older backup cameras typically had 300,000 pixels, resulting in very blurry images. Nowadays, whether for front-facing DVRs, … Read more
——Image source: National College Student Electronic Design Competition Training Network Since the last time, we talked extensively about power supply aspects. It feels like we discussed something, yet it seems like we didn’t cover much. The main point is that we really can’t say much. If I just drop a link, it would be purely … Read more
