地波场强计算,高频地波场强衰减计算，高频电磁波地波传播计算仿真，Fortran源程序，可以在cirr公开网址上获得。- The PC version of GRWAVE requires an IBM PC/AT or equivalent (80286 microprocessor) with a math co-processor and a minimum of 256 kilobytes of memory. Disk Contents: GRWAVE is supplied on a 3.5" or 5.25" disk which contains three main files. These are GRWAVE.EXE, GRWAVE.FOR and GRWUSR.MAN. GRWAVE.EXE is executable machine language code. GRWAVE.FOR is the FORTRAN source code. Compilation of this source code to produce an executable code requires a FORTRAN compiler which supports double precision complex arithmetic. Microsoft FORTRAN Version 4.01 was used to compile and link GRWAVE.FOR to produce GRWAVE.EXE. Compilation has also been tested with Lahey FORTRAN F77L [*]. It is known the IBM Professional FORTRAN will not work because of a lack of support for double precision complex arithmetic. [*] Note: GRWAVE uses a function, DREAL, which is not an in

说明：  用三个按键控制pwm输出 key0控制是选着显示/改变频率或占空比 key1控制增加 key2控制减少 数码管显示频率或占空比 频率单位默认Hz（500-20KHz） 占空比范围（0.1-0.9）(Control PWM output with three keys Key0 controls display/change frequency or duty cycle optionally Key1 controls the increase Key2 controls are reduced Digital tube display frequency or duty ratio Frequency unit default Hz (500-20khz) Duty cycle range (0.1-0.9))
