I am looking for cuircuit recommendations for high current MOS FETs with very low R(dson) used as high efficiency diodes with an extremely low forward voltage drop. As far as I remember, a fast single supply comparator was used to drive the MOS FET.
But what about a fullwave rectifier bridge...
What kind of radiation detectors are current state of the art concerning environmental detection of radio isotopes causing alpha, beta and gamma radioation these days? Are they still certain Geiger tubes or scintilation detectors or some more modern, maybe a semiconductor based scintilation...
Is there anyone who has experience with narrow band audio noise reduction with the SSM2000? This IC was designed for noise reduction of HiFi-audio but my application is noise reduction in the range of 300Hz - 3000Hz. Is there, beside DSPs, an analog alternative for the SSM2000 or an alternative...
I think of evaluating a preamplifier with an automatic level control for audio frequecies (aka: audio compressor)in the range of 300-3000Hz to give a DSP a relatively constant input level.
I came across the TDA4050B which is obsolete but still very cheap available. This IC has a dynamic range...
Hi,
we want to record a video signal from a video output of an elder HP-70206A spectrum analyzer. Its horizontal is 24kHz, its vertical frequency is 60Hz, with 1Vpp.
Now we look for a scan converter which scans and converts this signal to a video signal compatible with a PAL standard composite...
I am looking for an antenna which is intendet to be used to detect illegal cellphones in jailhouses. The policeman is walking up and down the corridors with the antenna and a small specrum analyzer to look for rf-signals (900-2500MHz). To lower the risk of a wrong indication, the antenna should...
I need to use a biconical antenna for a broad frequency frequency range (ratio 1:15). I recorded the antennas impedance chart: for the high frequencies it is something next to 50Ohm but for the low frequencies it is something far off and very capacitive. The antenna is just too small. But I have...
