The incoming signal is typically generated by an LFO or VCO but each signal with rising\/falling slope can be used (e.g. envelope generator or random voltage). Only for incoming rectangle signals the module does not make much sense. A typical application is a waveform generator that derives a rectangle signal with adjustable and modulated\u003cspan class=\"Apple-converted-space\"\u003e  \u003c\/span\u003epulsewidth (PWM) from an incoming triangle or sawtooth signal. That makes sense for LFOs or VCOs which do not offer this feature, e.g. A-110-4, A-145, A-147-2, A-143-4 or A-143-9.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"p1\"\u003e\u003cspan class=\"s1\"\u003eBut the module can be used for any kind of voltage comparison and takes many tasks of the no longer available moduled A-167.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"p2\"\u003e\u003cspan class=\"s1\"\u003e\u003cb\u003eThe module is equipped with these controls and in\/output:\u003c\/b\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli class=\"li3\"\u003e\n\u003cspan class=\"s2\"\u003e\u003c\/span\u003e\u003cspan class=\"s3\"\u003eManual PW control (PW), generates a DC offset voltage for the comparators\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli class=\"li3\"\u003e\n\u003cspan class=\"s2\"\u003e\u003c\/span\u003e\u003cspan class=\"s3\"\u003ePWM CV Input with attenuator (PWM)\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli class=\"li3\"\u003e\n\u003cspan class=\"s2\"\u003e\u003c\/span\u003e\u003cspan class=\"s3\"\u003eSignal input (In)\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli class=\"li3\"\u003e\n\u003cspan class=\"s2\"\u003e\u003c\/span\u003e\u003cspan class=\"s3\"\u003eOutput with LED control (Out)\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli class=\"li3\"\u003e\n\u003cspan class=\"s2\"\u003e\u003c\/span\u003e\u003cspan class=\"s3\"\u003eInverted Output with LED control (\/Out)\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli class=\"li3\"\u003e\n\u003cspan class=\"s2\"\u003e\u003c\/span\u003e\u003cspan class=\"s3\"\u003eInternal trimming potentiometer for PW (is adjusted for symmetrical 50:50 rectangle when the manual PW control is at center position)\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli class=\"li3\"\u003e\n\u003cspan class=\"s2\"\u003e\u003c\/span\u003e\u003cspan class=\"s3\"\u003eInternal trimming potentiometer for PWM range (is adjusted so that the manual PW control covers the full PW range 0 ... 100% in PWM application)\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli class=\"li3\"\u003e\n\u003cspan class=\"s2\"\u003e\u003c\/span\u003e\u003cspan class=\"s3\"\u003eThe trimming potentiometers are required to adjust the module for best operation for signals with different DC offsets (e.g. unipolar\/bipolar signals) and different signal levels in PWM mode.\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli class=\"li3\"\u003e\n\u003cspan class=\"s2\"\u003e\u003c\/span\u003e\u003cspan class=\"s3\"\u003eIn PWM mode the module is nromally assigned to another module because the trimming potentiometer have to be readjusted when the input signal changes (unless the signals have nearly the same DC offset and level)\u003c\/span\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Doepfer","offers":[{"title":"Default Title","offer_id":42997118369981,"sku":"1016128","price":109.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0526\/4175\/9421\/files\/DoepferA-168-1PWMModule.jpg?v=1742342353","url":"https:\/\/moogaudio.com\/products\/doepfer-a-168-1-pwm-module","provider":"Moog Audio","version":"1.0","type":"link"}
