function. The specific adjustment steps are as follows.I. Storage and extraction of Dual-Tone Multi-frequency CodesFor example, you can store and extract 12345 dual-Tone Multi-frequency codes as follows.1. Storage: First press the dial key (the user must be in use or repair status), the "P" sign appears on the screen, and then press the Moni key to display "P…" on the screen ..." You can press the 12345 numeric key, and the screen displays 12345 numbers. Then, press the dial key, and then scale

First, the basic knowledge of Bluetooth1. Bluetooth is a wireless technology standard that enables short-distance data exchange between fixed devices, mobile devices, and building personal domain networks. Bluetooth based device low-cost transceiver chip, transmission distance near, low power consumption.2. Microwave Band: UHF radio waves using ISM bands from 2.402GGHz to 2.480GHz (including protection band

ohms using parallel twelfth Wave Lines How produce ferrite RF transformers for various impedances transformation ratios? Ferrite TransformerImage shows a 1:1 transformer as blue and black wires windingsRatio is 1:1. This was for shortwave use. For VHF/UHF dimensions must is much smaller.Windings n1/n2 ratio by Square are transformation ratio for impedance:Example:za = ohms, Zb = ohms ...Na = 6 WDG; Nb = wdg + NA/NB = 6/12 = 0.5Transformation ra

I'll write it in the second blog article, this blog article just talk about water waves.Recently studied the water body, the effect as shown in GIF, at first glance feel can, but there are many residual, this example is written with surface shader, using the surface subdivision technology. Because of the surface subdivision, so surface shader vert can not be outgoing values, so the vertex coordinates and normal values can n

invisible electromagnetic wave crossing the space. The copper ring receiver suddenly looked a little strange. Hertz couldn't help shouting, and he put his nose in front of the copper ring, clearly, there seems to be a faint spark flashing in the air between Two Copper Balls. Hertz quickly ran to the window and pulled all the curtains. Now it is clearer: the gap between the pale blue electroflowers and the copper ring is constantly opening, while the whole copper ring is an isolated system, ther

, this section can be written here. It is the appearance of music in the time domain, but the appearance of music in the frequency domain. Therefore, the concept of frequency domain is no stranger to everyone, but never realized it. Now, let's look back and look at the first crazy dream: The world is everlasting. Simplify the above two figures: Time Domain: Frequency Domain: In the time domain, we observe the swing of the piano strings in a moment, just like the trend of a stock. in the frequen

understanding of music, a vibration that changes over time. However, I believe that the following is a more intuitive understanding of Music: Okay! Goodbye to the class. Yes. In fact, this section can be written here. It is the appearance of music in the time domain, but the appearance of music in the frequency domain. Therefore, the concept of frequency domain is no stranger to everyone, but never realized it. Now, let's look back and look at the first crazy dream: The world is everlasting. Si

blackboard: Fourier told us that any periodic function, can be seen as a different amplitude, different phase sine wave superposition. In the first example, we can understand that by using different strokes of different keys and different points of time, you can combine any piece of music. One of the methods through time domain and frequency domain is Fourier analysis of crossing. Fourier analysis can be divided into Fourier series (Fourier Serie) and Fourier transform (Fourier transformatio
