Why is Goertzel algorithm used?

The Goertzel algorithm is typically used for frequency detection in the telephone tone dialing (dual-tone multi-frequency, DTMF), where the meaning of the signaling is determined by two out of a total of eight frequencies being simultaneously present [5].

When would you use a bandpass filter?

Band-pass filter functions are used where it is desired to transmit signals in a certain band of frequencies and block signals of lower and higher frequencies. This is what is done in “tuning” a desired frequency, such as a radio or television signal.

What are the advantages of bandpass filter?

ADVANTAGES The main advantages of the Microphase designed and engineered Bandpass Filters are their narrow to wide passbands (up to one octave), featuring low Insertion Loss and VSWR, and sharp selectivity. You get excellent electrical performance, mechanical reliability and environmental stability.

Is it bandpass or band pass?

The passband of a receiver is the range of frequencies it can receive when it is tuned into the desired frequency (channel). A bandpass-filtered signal (that is, a signal with energy only in a passband), is known as a bandpass signal, in contrast to a baseband signal.
