goertzelTestTest the Goertzel filters for computing the discrete Fourier transform.
firTestTest the finite impulse response (FIR) filters.
iirTestTest the infinite impulse response (IIR) filters.
logicTestTest various comparison tests and Boolean functions.
miscIntOpsTest integer arithmetic operations.
AnyAsmForkstar is one of a group of stars that do produce any code at compile time.
DTMFPostTeststar used in touchtone decoding.
chirpThis system uses two integrators and a cosine to generate a chirp signal.
DTMFCodecDemonstration of touchtone detection using the discrete Fourier transform implemented by using Goertzel filters.
lmsA noise source is connected to an eighth-order least-mean squares (LMS) adaptive filter with initial taps specifying a lowpass filter. The taps adapt to a null filter (the impulse response is an impulse) and the error signal is displayed.
lmsDTMFCodecDemonstration of touchtone detection using Normalized Direct Frequency Estimation implemented by using Least-Mean Squares (LMS) adaptive filters.
phoneLineA telephone channel simulator. A tone is passed through some processing which implements various distortions on a telephone channel. The parameters that are controllable are: noise, channel filter, second harmonic, third harmonic, frequency offset, phase jitter frequency, and phase jitter amplitude.
sinA sine wave is generated by using two integrators in a feedback loop.
transmitterA simple 4-level PAM transmitter
