Bode plots – or frequency response graphs – are found in just about every piece of literature for high-end audio equipment. It’s a simple idea, graphing frequency over amplitude, … ...

Figure 3-2. An amplitude modulated signal. The demodulation process for AM where the radio frequency signal is converted into an audio frequency signal is very simple. It only requires a simple diode ...

Oscillation frequency is affected by waveshape and amplitude changes, but waveshape and amplitude are independent of frequency and each other. Therefore the easiest setting method is to adjust ...

Instead, they should have an adjustable top value and a separately adjustable bottom value: 5V and 0V, for example. The other day, I thought of a way to modify a conventional ‘diamond buffer’ (circuit ...

In National 4 Physics examine the properties of waves and use the wave equation, v = f λ, to relate the speed, frequency and wavelength.
