FSK Modem
This example shows frequency shift keying (FSK), a type of frequency modulation in which the modulating signals shifts the output frequency between two predetermined frequency values.

Heterodyne
This example demonstrates double-sideband (DSB) modulation, also called signal heterodyning or signal mixing. The example also displays the modulated signal and uses the target hardware to output the signal.

AM Modulation - Demodulation
This example shows amplitude modulation and demodulation of a signal. The carrier signal's amplitude varies with the content of the message signal by heterodyning the two signals together. Demodulation uses squaring and lowpass filtering to recover the message signal.

Automatic Gain Control
This example shows how to use the AGC VI to apply an automatic gain control (AGC) algorithm to an input sine waveform signal on the DSP target. The Embedded Sine Waveform VI generates a sine wave with an adjustable frequency and amplitude.

Bandstop Filter
This example shows how to use an FIR bandstop filter to alter the frequency of a signal. The DSP target generates a sine wave with an adjustable frequency and the Bandstop Filter VI adds an analog signal to this DSP target signal.

Biquad Filter
This example shows how to use two Biquad VIs to implement a digital fourth-order Chebyshev lowpass filter. On the front panel of the Biquad Filter VI you can see the original signal and the filtered signal in the time domain and frequency domain.
