... The goal is to verify that the conceptually simpler modulation scheme described by eq. (1), and shown in the figure at the top of p. 2, is undesirable. To study this you need to generate a waveform like that on the lefthand side of the figure at the top of p. 2. Borrow a 2nd Wavetek generator and se ...

... The IF amplifier has a tuned circuit that accepts components only near 455kHz, in this case 454kHz, 455kHz and 456kHz. Since the mixer maintains the same amplitude proportion that existed with the original AM signal input at 999kHz, 1000kHz and 1001kHz, the signal now passing through the IF amplifie ...

It turns out that the sinusoid masquerades as one of another frequency. Consider the situation when the frequency f of a continuous-time sinusoid is ...

... For single-supply applications (VS− = GND), the input voltage range extends from 100 mV below ground to within 2.0 V of the most positive supply. Each filter input includes level-shifting circuitry. The level-shifting circuitry adds a dc component to ground-referenced input signals so that they can ...

When the anti-aliasing filter is being discharged, the differential op-amp sees a 20 Ω differential load. This is an acceptable load for the ADA4938-1. ...

We all understand that relative low impedance at the electrode sites will demonstrate a better output quality, but this would not be true if the input impedance at the amplifier was not inversely high. This is bec ...
