Interfaces

freqmod freqmod_create(float _kf)∞

Create freqmod object with a particular modulation factor

• _kf : modulation factor

int freqmod_destroy(freqmod _q)∞

Destroy freqmod object, freeing all internal memory

int freqmod_print(freqmod _q)∞

Print freqmod object internals to stdout

int freqmod_reset(freqmod _q)∞

Reset state

int freqmod_modulate(freqmod _q, float _m, float complex * _s)∞

Modulate single sample, producing single output sample at complex baseband.

• _q : frequency modulator object
• _m : message signal \( m(t) \)
• _s : complex baseband signal \( s(t) \)

int freqmod_modulate_block(freqmod _q, float * _m, unsigned int _n, float complex * _s)∞

Modulate block of samples

• _q : frequency modulator object
• _m : message signal \( m(t) \), shape: (_n, 1)
• _n : number of input, output samples
• _s : complex baseband signal \( s(t) \), shape: (_n, 1)
