Zero on the meter scale was defined as where the needle points when a 1-mW pure sine wave audio signal at 1000 Hz is placed across a 600 Ω load. This point ends up about two-thirds of the way ...

Carrier Wave Generator The Wave Generator creates a high-frequency radio signal. The frequency of this signal is many times greater than the frequency of the audio wave. This signal will "carry ...

Pulse counting works by generating a narrow, fixed-width square wave pulse at a set point ... we can tease out the original audio frequency signal. Simple in theory is often more complicated ...

waveform, or noise source. Signal generators can use AC energy, audio frequency (AF), and radio frequency (RF) to function. They are also used to troubleshoot various electronic devices and to measure ...

The difference is in how the carrier wave is modulated ... slight changes in amplitude don't matter -- since the audio signal is conveyed through changes in frequency, the FM receiver can just ...

When analog audio signals are used to modulate a radio wave, the high frequency components of the audio signal are emphasized (called pre-emphasis) to allow the modulator to be more effective. Because ...

This concise overview of digital signal generation will introduce you to powerful, flexible and practical digital waveform generation techniques. These techniques, based on phase-accumulation and ...
