dBu是度量模拟信号的,而dBFS是度量数字信号的,并且dBFS不会用于度量模拟信号,所以没有在dBu和dBFS之间没有统一的转换公式,依赖于具体的数字设备。在dBu和dBFS转换时,需要规定一个峰值电压,该电压下产生的音频信号经过AD转换后得到的sample为0dBFS。例如,+18dBu对应于0dBFS,在该条件下 求 xdBu对应于ydBFS,那么就有...

DBW In the field of decibels, the basis of the reference is clear at 1W db. For audio, such as microphone level level and linear level level (Line Level), the use of dBm to calculate the value is just right, if imported with dBW is not appropriate, it is too large. We only ...
The reference level is −18 dBFs. 0 dBFs is equal to +15 dBu. Notice: 0 dBFS is the permitted maximum digital level. The EBU broadcasters have a problem, because they want to use the old slow meters with the dBu scale (attack 10 ms, quasi-peak) of the analog times for digital re...
For example: Copy Copied to Clipboard Error: Could not Copy DBAccessor dba = new DBAccessor("ora"); DBEntity dbe = new DBEntity(dba, "dbhost.sun.com", 1521, "IAS"); DBUser dbu = new DBUser(dbe, "scott", "tiger"); Concept 2: Create a DBUser instance in a two-step sequence:...
该器件的其它特性包括10 V/µs的压摆率和宽带宽。在整个音频频段内,总谐波失真(THD)低于0.004%,即使驱动低阻抗负载时也是如此。SSM2143输入级设计用于处理高达+28 dBu的输入信号(G = 1/2)。虽然该器件主要针对G = 1/2的应用,但通过反接+IN/-IN和SENSE/REFERENCE,也可以实现2倍增益。
telephone receiver. As it happens, when 1mW of power is dissipated in 600 Ohms, the voltage across tat termination happens to be 0.775V rms — and that's what we still use as the reference for dBu, but without the need for a 600 Ohm load (the 'u' actually stands for 'unterminated'...

spanning the range from -14dB to +6dB. Unity gain is marked at the two-o'clock position. The third silver knob determines the threshold level for the Soft Stop adjustable peak limiter. The knob is scaled from +24dBu to -6dBu, so setting a specific maximum output level is simple. Turni...
