Add a signal strength display to an FM receiver IC:
09/05/2002 EDN - Design Ideas / The Philips (www.semiconductors.philips.com)
TDA7000 integrates a monaural FM-radio receiver from
the antenna connection to the audio output. External
components include one tunable LC circuit for the
local oscillator, a few capacitors, two resistors,
and a potentiometer to control the
variable-capacitance-diode tuning..
IC Forms Differential Line Driver / Receiver:
05/25/95 EDN-Design Ideas / you can use the HFA1212
dual video buffer to implement differential line
drivers and receivers with a minimum of external
components
Infrared Receiver for Sony Remotes: receive
signals from a standard Sony remote control and send
the code bytes(2) received to an RS-232 port, based
on PIC16C84
Simple CATV Upstream Fiber Optic Receiver Uses DC
Pilot AGC: 01/20/03 Electronic Design - Ideas
for Design / Upstream fiber links in a community
antenna television (CATV) system are usually among
the most difficult elements of the network to align
properly. Set-top boxes and cable modems employ
"long-loop" automatic gain control (AGC) (in other
words,...
Simple Circuit Detects Current Pulses: 01/06/94
EDN-Design Ideas / The pulse detector provides a
visible indication of positive and negative current
pulses. The pulses amplitudes can vary from20 to150
mA. The pulses durations can range from10 to40 msec,
and their repetition rate can span40 to180
pulses/minute.
