虽然最初就想到对于宽频带的应用,但是线性转换(线性化传导)技术已经证明具有满足或超过象脉冲调制那样低的带宽方案的精确度的能力。利用这个技术的现代产品所提供的误差在满刻度的(FS)低于±0.1%,用于模拟运算,这些通常有高电平(±10VFS)输入/输出,提供四象限操作和具有约1MHz的频带宽度。 新的结构已发展以求满足各别不同的宽带信号控制应用的需要(在许多方面得到挑战)。象AGC回路精确度,噪声减小系统,视频混频器/混频电位器等等。图1表示了这些普通倍增器的方框图。
Although initially thought of for wide band applications, linear conversion (linearization) techniques have proven their ability to meet or exceed the accuracy of bandwidth schemes as low as pulse modulation. Modern products using this technology provide errors of less than ± 0.1% of full scale (FS) for analog operations, which typically have high levels (± 10VFS) of input / output, four-quadrant operation and about 1MHz Of the bandwidth. The new architecture has evolved to meet the needs of a variety of different broadband signal control applications, which are challenged in many ways. Like AGC loop accuracy, noise reduction systems, video mixers / mixer potentiometers and more. Figure 1 shows a block diagram of these common multipliers.
